Re: [Serusers] SER+Asterisk+NAT. Need a working example or need to talk about it.

Dear Alexey: Yes, there are almost no document about ser 0.9.0 above. And I am only using the post from Paul's example ser.cfg for 0.9.0 long time ago. I ever study about ser and asterisk at http://www.voip-info.org/wiki-Asterisk+at+large And I also need noanswer and busy forward functions in my scenario. I almost lost hope to do that. Is it necessary to use Radius on ser + asterisk ? I have just a little knowledge about radius, so I am afraid of it. Thank you for your reply and wait for your config files. :-) Charles On Tue, 22 Feb 2005 10:06:26 +0200, Alexey N.

[Serusers] Prepaid method ???
by Charles Wang 22 Feb '05

22 Feb '05

Dear ALL: I want to implement a prepaid (for PSTN) ser sip solution. But there are serveral questions in my mind: 1. Is it possible to force to tear-down the call properly? Can I use asterisk or b2bua only if I don't want to do it on trunk? 2. In mediaproxy+rtpproxy mode, I know there is a sub-project under "ser/sip_router" named "rtpproxy". Does it must be start when I want to implement mediaproxy+rtpproxy? Or does the mediaproxy Python server have its own rtpproxy? 3. Do I must modify the acc module or a new module to write the cdr and billing for this goal? Because acc module only writes INVITE and BYE to acc table, and it will not calculate the call during time. Is there an another method to implement it? Best Regard Charles

[Serusers] Is it possible to be a distributed SER modules system?
by Charles Wang 22 Feb '05

22 Feb '05

Dear ALL: I know that I can have many mediaproxies and choose one of them to route via DNS SRV method. And in the implement of vovida, almost all its servers(such as fs, ms, rs) can be put on different locations(sites / servers) and access them via setting correct URLs and their ports. Does SER sip have the same characteristic? I can use the registar or acc module of A and work for ser B?

Re: [Serusers] "Best practice" document, was Warning: sl_send_reply: I won't send a reply for ACK!!

Perhaps, but I think we really need to focus on ser-0.9 rather than the unstable cvs code. The exception might be the LCR module because it is an extremely important piece of functionality which can in many cases make a CLEC / VoIP player profitable or not. Anyhow, to remain focused I think we should focus on ser-0.9 only.

[Serusers] 0.8.14 with RADIUS on Debian.
by Rod Bacon 21 Feb '05

21 Feb '05

Has anyone had any luck building the latest SER version on Debian stable with RADIUS and SQL enabled? I have replaced all the debian RADIUS libraries with the new RADIUS-NG, and amended all the debian build scripts (as the ones that come with 0.8.14 still refer to the older libraries) but I think I've missed something somewhere, as I have all sorts of library problems. I'd be interested in hearing from anyone who has this combination of SER/RADIUS/DEBIAN. Cheers.

Re: [Serusers] SER SDP Port Problem??

Hi Greger, I only use nat_uac_test("3") as that is what is given in most examples on the mailing list. Is there any way that i can test if I am behind symmetric nat?

Yeah, but the nonce expiry time is included in the reponse to the client, so it will know whether the nonce has expired or not. I believe it is grandstream 100 that has showed this behavior, but only for a certain firmware or combination of settings, haven't been able to nail it down. g-) > Klaus Darilion wrote: >> Greger V.

Hi Greger! Greger V. Teigre wrote: ... > Agree. We use RADIUS-based authentication and authorization with > distributed RADIUS servers. Only usrloc is stored in mysql (we use I want to ask about your radius experiences. We (www.at43.at) are also using radius authentication. All the radius requests are sent to a local radius proxy which forwards the request to the radius server of the participating groups (universities, schools ...). If one of the remote radius servers is down, we are having problems with ser. Ser's threads are busy, waiting for the radius authorization responses and ser is slowing done. Then, the client starts to retransmit their REGISTER messages and ser is getting busier and busier until all threads are busy with authentication requests. Thus, the complete service will be down only if one of the radius servers is down. We have reduced the proxy load by replying "100...trying" to all REGISTER requests, which reduces retransmissions in case of slow authentication. We also tried to tweak the radius retransmission and timeout settings but could not find a satisfying solution yet. Do you also have problems in your distributed radius setup? Maybe you could post a little about your experience with distributed radius. All other radius users are also welcome to post their radius experiences. regards, klaus PS: I hope Maxim's patch for stateful authentication is going into 0.9.0

Uncomment "DEFS+=-DSQL_ACC" at modules/acc/Makfile and recompile the mysql.so. Then using modparam("acc", "db_url", "sql://ser:password@localhost/ser") or modparam("acc", "db_url", "mysql://ser:password@localhost/ser") to test it.

21 Feb '05

Hi, I want to use SER to Rasius authenticate, radius accounting. I read too many documents but not able to get a good configuration. My scenerio is simple. - Register SIP clients via Radius Auth. - Route the call with respect to prefix (is it possible to get from radius?) or some other methos instead of direct CFG config. - radius accounting (start/stop) have a working cfg file ?

[Serusers] SER SDP Port Problem??
by Aisling O'Driscoll 21 Feb '05

21 Feb '05

Hi, I understand the basic problem behind one way audio is that the client behind nat has a private address in the sdp information, therefore the voice cannot be delivered to this private address. It is necessary to rewrite this sdp info with the nat public address. However I have done this in my ser.cfg and I still have one way voice. I have included some of relevant ethereal messages on SER and my ser.cfg below. The messages show that the rtp information has been changed. Does anyone think the problem is because there is no port information in the "c" and "o" fields in the sdp?? If so how can I make sure the port is included? Many Thanks, Aisling. Ethereal messages: call between private client with public nat address 63.218.54.71 and a public client with address 157.190.183.80. The SER address is 157.190.183.70.

[Serusers] Security methods for PSTN termination of SIP calls
by Alan Litster 21 Feb '05

21 Feb '05

Hi, When providing PSTN termination of calls that originate from a SIP source how do you go about validating the identity of where the calls originated from - the SIP Proxy or the SUA. PSTN ---- SIP Proxy 1--- + --- SIP Proxy 2 ---- PSTN So the calls originate from the PSTN in a country, get transported across the internet and terminated in a different country via another company. Other than source IP address, what method could you use to validate the origin of the calls? Also in question is security for trunk services for companies that simply want to terminate calls out onto the PSTN. How can you setup a trust relationship between the two proxies? Is any one here in a similar situation??

[Serusers] Has any idea to disconnect a connection?
by Charles Wang 21 Feb '05

21 Feb '05

Dear ALL: If an UA1 ( Under NAT / Public Network) make a call to another UA2( Under NAT / Public Network), is there any idea to disconnect it after xx seconds? For example, the UA1 has 300 seconds credit, and this call can only keep maxinum 300 seconds. Charles

Hi all, I'm running ser 0.8.14 with nathelper+rtpproxy. I can initiate calls from UA behind NAT to UA in public without problem.

[Serusers] NAT, rtpproxy and STUN
by Rod Bacon 21 Feb '05

21 Feb '05

After having good success with STUN (on a separate server) as a method for traversing NAT from many devices, I am endeavouring to get rtpproxy and nathelper configured as a fallback scenario for devices with no/poor STUN support. The issue I have is that calls from a UA using STUN to a UA registered via nathelper don't transmit/receive any audio information, I assume because the call does not traverse the proxy. Calls the other way are OK, as I am setting a 'natted' flag and forcing rtp_proxy based on that event (e.g. a UA handled via Nathelper CAN call a STUN serviced UA, but not the other way around). Is there any way to set proxying on/off based on the CALLED UA, not the CALLING one? Can I test to see if a given UA registered via Nathelper, and then enable proxying for all calls to that UA? Am I even making sense? -- ========================================== Rod Bacon - VOIP Systems Engineer Empowered Communications Ground Floor, 102 York St. South Melbourne Victoria, Australia. 3205 Phone: +613 99401600 Fax: +613 99401650 FWD: 512237 IAXtel: 17007401708 ==========================================

[Serusers] Questions on using ser.cfg version 0.9.0 for call forward/busy/noanswer
by Charles Wang 21 Feb '05

21 Feb '05

Dear ALL: I insert records to my usr_preferences as below: In usr_preferences table: username domain attribute value ------------------------------------------------------------------------------------------------------------------- 1022 ser.xxx.net.tw donotdisturb n 1022 ser.xxx.net.tw voicemail n 1022 ser.xxx.net.tw anoncallrej n 1022 ser.xxx.net.tw callidblock n 1022 ser.xxx.net.tw callfwd sip:0939749xxx@ser.xxx.net.tw 1022 ser.xxx.net.tw fwdnoanswer sip:0939749xxx@ser.xxx.net.tw 1022 ser.xxx.net.tw fwdbusy sip:0939749xxx@ser.xxx.net.tw In grp table: username domain grp --------------------------------------------------- 1022 ser.xxx.net.tw int 1011 ser.xxx.net.tw int Now, I change my value to sip:0939749xxx@ser.xxx.net.tw. If its attribute is "callfwd", the call will be forward to my mobile phone(0939749xxx) using route(3) to PSTN. So the result is OK. I delete the attribute "callfwd" in order to test "fwdnoanswer" function. If UA 1011 make a call to UA 1022 and UA 1022 no answer, it should goto failure_route[1] and make a call to route(3) depending on its "uri" (phone number). And I also find it runs to failure_route[1] and jump to route(3). But the connection will disconnect for a few seconds. And displays "408 Request Timeout" on my X-Pro Client. I find it jumps to another route(2) after disconnect. I know I should not disturb you too much because of your works and your new best example cfg file for us. But can you please help me to discover what reason about it. I think it should be the reason in my TM modules. I am a Taiwanese and using a poor English.
