[Serusers] append_hf_helper brings strange characters.
by szj 22 Mar '05

22 Mar '05

I use the SER 0.10.99 version. I want to modify the procedure of tm module. Before sending the request and forwarding the reply, I managed to modify the request and response, f.e, to insert another header into the request and response. In the request, it works correctly.But in the response, sometime it works, sometimes it failed. The debug log is as follows. 2(2196) old size: 784, new size: 869 2(2196) build_res_from_sip_res: copied size: orig:76, new: 161, rest: 708 msg= SIP/2.0 200 OK^M >P-Security-Nobody:Zgrrv1Y/19zYJGyKXm4obgHZZP5jY59qxbhLxEUgZO11uI41w1QzJKqSbjYQ6G7e/ViClnetse/aCE+dj/TbAZFQa45dL/wPzAS4MDKABos=^M >/QjFhTWNKQaL8k=^M/*<90>*Via: SIP/2.0/UDP 192.168.0.19:5500;branch=z9hG4bK1648283653^M Record-Route: <sip:192.168.0.19;ftag=549451184;lr>^M From: <sip:861111@sip.suntest.com>;tag=81929894;tag=549451184^M To: <sip:862222@sip.suntest.com>;tag=882426148^M Call-ID: 903055665(a)192.168.0.19^M CSeq: 21 INVITE^M Contact: <sip:862222@192.168.0.19:6600>^M Allow: INVITE, ACK, OPTIONS, CANCEL, BYE, SUBSCRIBE, NOTIFY, MESSAGE, INFO^M Content-Type: application/sdp^M Content-Length: 261^M ^M v=0^M o=nobody 20041028 20000001 IN IP4 192.168.0.19^M s=A call^M c=IN IP4 192.168.0.19^M t=1111396796 1111400396^M m=audio 7100 RTP/AVP 0 8^M a=rtpmap:0 PCMU/8000^M a=rtpmap:8 PCMA/8000^M m=video 7600 RTP/AVP 98 31^M a=rtpmap:98 H263/90000^M a=rtpmap:31 vf=4/CIF/1/768^M I insert the header "P-Security-Nobody: " into the response using the modified version of function "append_hf_helper". There are some strange code in the backend of inserted header. f.e, the italic black characters in the log. I had added a null terminator at the tail of the inserted header. I guess it is caused by the data_lump functions. Who can tell me the real reason of that? Thanks for your kind help. Best Regards. Sun Zongjun

[Serusers] getting "error: 400; check if you use aliases in SER" when adding a new user with serctl

Hi list maybe this is an stupid question but I can't find any clue what I'm doing wrong. When I try to add a new user using serctl add I'm getting the following error: error: 400; check if you use aliases in SER What does "error: 400" mean? I have looked it at messages and I'm no receiving any log information. I'm using two aliases at my ser.cfg I'm attaching my ser.cfg How should I handle this error?

[Serusers] Why Does SER Keep Retransmitting "487 Request Terminated" Messages?
by Java Rockx 21 Mar '05

21 Mar '05

Hi All. I don't know if this problem is related to the re-INVITE problem I posted yesterday http://lists.iptel.org/pipermail/serusers/2005-March/016961.html But it seems that when our Sonus PSTN gateway is invovled in a call where the SIP UA sends a CANCEL before the other party answers, that ser restransmits 487 messages to the SIP UA. When dialing SIP->SIP everything works fine, it's just when the Sonus GW is being accessed that the problem surfaces. It appears that everything has been ACKed, so I'm stumped as to what is happening here. The attached call log shows the complete dialog where my Grandstream UA dialed a PSTN number and cancelled the call when the other side was ringing. Can anyone give me a pointer as to why this might be? Regards, Paul

Yes, I am doing ... but there wasnt any non-successfull reply in the scenario mentioned. Also, mediaproxy does terminate the session based on Call-ID (correct me if I am wrong) and it terminates the session completely, ignoring branches.

[Serusers] To and From Headers - Angle Brackets Or Not
by Java Rockx 21 Mar '05

21 Mar '05

Hi All. I'm using ser-0.9.1. Does anyone know if angle brackets are required around the TO: and FROM: headers? Our Sonus gateway sometimes omits these brackets and I just want to make sure that SER correctly identifies SIP transactions. Here is a PSTN->SIP INVITE that shows the brackets being omitted.

HI, I have installed SER 0.8.14 + MEDIAPROXY : when I make a call with 2 UA on different NAT, it's good. But, when the UAs are behind the same NAT, there are no sound. The RTP packets go to the MEDIAPROXY but NO SOUND. Does someone know how to solve this problem???

[Serusers] Troubles calling from a Nated UA to a PSTN gateway on a Public address space using SER 0.9.1 and Mediaproxy Release 1.2.1
by Alberto Cruz 21 Mar '05

21 Mar '05

Hi everybody I having a weird behavior with Mediaproxy I'm using SER 0.9.1 and Mediaproxy Release 1.2.1 The Gateway is a Cisco AS5300 using release 12.2(15)T I have a UA using behind a NAT, the PSTN gateway and the SER server both are using public IP addresses. The behaviors are the following: 1. When I tried to place a call from a NATed UA to the PSTN gateway I'm not receiving the call progress tone or ring back tone at the NATed UA. 2. If I decide to wait until the call is completed (doesn't matter if a heard death air as progress tone) I start hearing the calling party as soon the call is completed and we can talk each other without any troubles. 3. If I cancel the call and hang up the phone at the NATed UA before the call is completed (during the call progress stage) the SER/Mediaproxy don't cancel the call it still in progress until it is completed or cancelled by the PSTN. I'm attaching my ser configuration and the logging I'm getting when I cancel the call before it's completed.

[Serusers] SER Radius Accounting - Two Start Messages for Every Call
by matt morris 21 Mar '05

21 Mar '05

Hello List, I got a problem with ser radius accounting. Seems ser sends two start messages to my freeradius server (ser 0.10.99-dev5, radiusclient-ng 0.5.0 and freeradius snapshot 20050315 in the same computer) for every calls I made, and also for missed calls (two same failed message). Does it have to do with my dictionary file(s)? For my ser.cfg, I only set the radius_flag to be 1 and radius_missed_flag to 2. I only called setflag(1) once with this if condition before record_route(): if (method=="INVITE" || method=="BYE") { setflag(1); }; Did not have this problem when I used db_flag There are another two users with this same or similar problem, but there is no answers to their thread. So wondering if they have solved it or anyone else know why is it behaving like this? Please help me out, thank you.

[Serusers] Mediaproxy and parallel forking
by Enthu 21 Mar '05

21 Mar '05

Hi, I was trying parallel forking with ser and Mediaproxy. Here is the scenario. Party Proxy Location A Location B | INVITE | | | |------------>| | | | 100 | | | |<------------| INVITE | | | |-------------------> | | | | INVITE | | | |----------------------|---------------->| | | 180 (w/o sdp) | | | |<----------------- | | | | | 180 (w/sdp) | | |<-------------------------------------- | | | 200 | | | |<-------------------| CANCEL | | |---------------------|---------------->| | | | 200 | | |<--------------------------------------| | | | | When I get 18X response I am doing "use_media_proxy" and Location B starts sending early media. When call is picked up at Location A, Calling party still gets early media from Location B. After Location B receives CANCEL, it stops sending media and media proxy shows idle session on one end. This combination is always failing to work. If both locations are uniform and dont send early media, parallel forking is working great. Do any of you come across this situation? Am I doing anything wrong here? I apologise if my query sounds stupid. thanks in advance. Enthu

Yes. Mediaproxy and rtpproxy receive RTP data and forward it on to the other party in the call.

Hi Juha, I thought that LCR module is only used to try a list of PSTN gateways or SIP proxies so I didn't look for a multi-forwarding solution using this module. Maybe I should take a look at it. Could you please confirm that with this module ser can load a list of destinations for each SIP request based on TO, FROM or RURI of the sip message? Thank you for your help.

Hi all, Thanks you for your help. I think I can implement a multi-forwarding service now but I think I should spend sometime trying to add some ordering mechanism to avpops module because basing on order from database is not enough for such kind of service.

If you want to have ordering for AVP of same name/ID at load_db time you need to relay on some information/order already existing in the DB.

The revert order is a effect of how the AVP core is implemented - the AVPs are kept in singled-linked list and any new APV is added at the beginning of the list.

[Serusers] Troubles calling from a Nated UA to a PSTN gateway on a Public address space using SER 0.9.1 and Mediaproxy Release 1.2.1
by Alberto Cruz 20 Mar '05

20 Mar '05

Hi everybody I having a weird behavior with Mediaproxy I'm using SER 0.9.1 and Mediaproxy Release 1.2.1 The Gateway is a Cisco AS5300 using release 12.2(15)T I have a UA using behind a NAT, the PSTN gateway and the SER server both are using public IP addresses. The behaviors are the following: 1. When I tried to place a call from a NATed UA to the PSTN gateway I'm not receiving the call progress tone or ring back tone at the NATed UA. 2. If I decide to wait until the call is completed (doesn't matter if a heard death air as progress tone) I start hearing the calling party as soon the call is completed and we can talk each other without any troubles. 3. If I cancel the call and hang up the phone at the NATed UA before the call is completed (during the call progress stage) the SER/Mediaproxy don't cancel the call it still in progress until it is completed or cancelled by the PSTN. I'm attaching my ser configuration and the logging I'm getting when I cancel the call before it's completed. Please let me know if this behavior is because I'm making some mistake with mediaproxy configuration. Thanks in advanced.

[Serusers] how to sort data retrieved from avp_db_load in avpops module
by PHAN, Quang-Minh (Docteur Ordinateur) 20 Mar '05

20 Mar '05

Hi List, I want to implement serial forking with avpops module and I have this problem. The set of destinations for each user is stored in a database and I use apv_db_load to load it. However, I couldn't find a way to sort them in the right order. For example, I cant tell SER to try destination A before B, then C because there is no way to specify this in the database. Another feature I want to implement is to allow a client to specify a timeout for a destination. Eg. Try A for x seconds, then try B for y seconds, then try C. I wonder if there are ways to implement the services above using actual ser modules or it's not yet possible. Best regards, Minh

Hi All. Is it possible for ser to write received SIP traffic that causes "serctl moni" to show a failure? If I understand this correctly, a "failure" will never reach the processing in ser.cfg so I cannot just use xlog or something to write out the message that caused the failure. Regards, Paul

[Serusers] NAT & nathelper w/o rtp proxy
by Martin van den Berg 20 Mar '05

20 Mar '05

Hello Gurus, I'm running a lill' SER server(to which I am a newbe) here behind NAT. The NAT setup is, I beleive, quite simple: the server is on 192.168.1.3, the router is at 192.168.1.1 and the public IP address is A.B.C.D. All calls/SIP requests originate from the public network. I do not want to relay RTP. >From what I understand, I need to use the nathelper module. I've got a script that *should* do something but SER reports "ERROR: send_rtpp_command: can't connect to RTP proxy". Does nathelper always require a RTP Proxy? Or, can this be done w/o nathelper? Thanks! Martin

[Serusers] clients not responding to challenges?
by maka 19 Mar '05

19 Mar '05

Hi all, does anyone know what the reason might be for SIP clients (XLite and other) on certain Ip addresses not responding to the www_authenticate() challenges sent by the Sip proxy? I can see (with ngrep) that the clients send register requests to SER, and I also see SER sending back challenge packets. Anyway, no challenge response is sent back from the client, but a normal REGISTER. XLite diagnostic log does not show any challenge request packets being received by the client. My first assumption would be a routing problem between the ISPs networks, but this all happened suddenly after a restart of my SER machine, even though nothing on the configuration has been changed. On some machines(resp. ISPs), the client registers successfully and can dial out other SIP clients, but does not receive any incoming calls. On other - everything works perfectly both ways. Pls give me any clues or suggestions if u can...

Hi ALL, I am a newbie on DNS configuration stuff, so need help to configure DNS SRV record for SER installation. For it, I just added following two lines to the concerned zone file: sip.mydomain.com. IN A ip.ad.re.ss _sip._udp.mydomain.com. SRV 0 0 5600 sip.mydomain.com. Then I restart DNS(BIND) by Plesk.(Is there a problem?) And I did and got: # dig sip.mydomain.com :It was answered correctly # dig _sip._udp.mydomain.com :It was answered correctly # dig -t SRV _sip._udp.mydomain.com :No answer. Is there something wrong? Or am I missing something here? I would really appreciate your help. Thank you, Jay Lee
