[Serusers] Mediaproxy and parallel forking

by Enthu

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

Re: [Serusers] NAT & nathelper w/o rtp proxy

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

RE: [Serusers] how to sort data retrieved from avp_db_load in avp ops module

by PHAN, Quang-Minh (Docteur Ordinateur)

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.

by PHAN, Quang-Minh (Docteur Ordinateur)

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

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)

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

[Serusers] Can I syslog serctl moni failures

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

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
