RE: [Serusers] RTP Proxy and SER

Thanks for that, I'll get the source from the CVS and give it a go. -----Original Message----- From: Andrei Pelinescu-Onciul [mailto:pelinescu-onciul@fokus.fraunhofer.de] Sent: Tuesday, 28 October 2003 10:05 a.m. To: Stephen Miles Cc: serusers(a)lists.iptel.org Subject: Re: [Serusers] RTP Proxy and SER On Oct 28, 2003 at 09:54, Stephen Miles <smiles(a)callplus.co.nz> wrote: > Hi Andrei, > > I have the nathelper module being loaded but am still getting an error. > Here is my log, can you shed any light on this for me? Yes, force_rtp_proxy exists only in the nathelper module from ser unstable (cvs HEAD). Sorry I didn't notice the part about using ser debian packages (which implies you use ser stable). You could try getting ser unstable sources and compiling it, however right now we are doing a lot of changes and the current cvs might be broken. It is probably safer to use a version from 2 weeks ago. Andrei

[Serusers] How does SER's Stateful Proxy works?
by Dharani Narayanan 27 Oct '03

27 Oct '03

Hello I went through few modules of SER regarding the session maintenance. When i walked through the Transaction Module, I came to know that SER provides Stateful Proxy. I have few questions regarding this: 1. How does SER maintains session? i.e., Does it maintain any state table similar to file/socket descriptor? 2. In the case of "dialog" interaction between clients are identified by callID and routed through the Record-Route. Does Record-Route traces the session? If so where it is maintained? Will this become a overhead in header while routing all the details? Does the client feel efficient in performance? 3. How does SER knows whether the session is disconnected or logged off? And under what situation does the SER stores the offline messages? 4. Can you provide me the total architecture of how the stateful proxy is designed and works? Can you please update me for the above mentioned questions. Thanks Dharani. __________________________________ Do you Yahoo!?

[Serusers] ser does not respond to messages with NATed address
by Yang Xiang 27 Oct '03

27 Oct '03

Hello, I have a NATed network behind a cisco PIX firewall as follows: client --- SER 1-----PIX (NAT) --------SER 2 The client has a private address 192.168...., and is NATed to a public IP. Because PIX has a bulit-in SIP-application-gateway, the IP of the client in message body will be transformed to his public IP by firewall.. However, what most strange is SER2 doesn't respond to messages from SER1. -------------- #################### U 153.96.51.2:5060 -> 153.96.52.2:5060 INVITE sip:6091@153.96.52.2:5060 SIP/2.0..Record-Route: <sip:6091574@153.96.51.2;ftag=781a5806-7443-4c67-b8a6-4ae6f9b64bc8;lr=on>..Max-Forwards: 9 . .Record-Route: <sip:6091@192.4.3.2;ftag=781a5806-7443-4c67-b8a6-4ae6f9b64bc8;lr=on>..Via: SIP/2.0/UDP 153.96.51.2;branch=z9hG4bK75cf.a543.0..Via: SI P/2.0/UDP 192.4.3.2;branch=0..Via: SIP/2.0/UDP 153.96.51.77:9779..From: "xia" <sip:xia@nd.fhg.de>;tag=781a5806-7443-4c67-b8a6-4ae6f9b64bc8..To: <s ip:6091@nd.fhg.de>..Call-ID: 9947a08e-d8c5-47ef-90a3-cdd10f3b143c@153.96.51.77..CSeq: 1 INVITE..Contact: <sip:153.96.51.77:9779>..User-Agent: W indows RTC/1.0..Content-Type: application/sdp..Content-Length: 457....v=0..o=yang-mobil 0 0 IN IP4 153.96.51.77..s=session..c=IN IP4 153.96.51.77..b=CT :1000..t=0 0..m=audio 61052 RTP/AVP 97 111 112 6 0 8 4 5 3 101..a=rtpmap:97 red/8000..a=rtpmap:111 SIREN/16000..a=fmtp:111 bitrate=16000..a=rtpmap:112 G7 221/16000..a=fmtp:112 bitrate=24000..a=rtpmap:6 DVI4/16000..a=rtpmap:0 PCMU/8000..a=rtpmap:8 PCMA/8000..a=rtpmap:4 G723/8000..a=rtpmap:5 DVI4/8000..a=rtp map:3 GSM/8000..a=rtpmap:101 telephone-event/8000..a=fmtp:101 0-16.. ---------------------------------------------- (originally the client has an IP 192.168.44.33 and it has been transformed to 153.96.51.77 by firewall as seen above) SER2 gets all messages repeatedly from SER1 but does nothing as if it hadn't seen any messages.

Re: [Serusers] multiple users registering problem

There may be lot of reasons why the old contact disappears. A typical reason is that the old contact expires after its expiration period.

[Serusers] SER and inter-domain routing
by Alexandru Deac 27 Oct '03

27 Oct '03

Hello, This might be a trivial issue, but I can't think of a solution to it. I have a SER installed on a linux machine acting as proxy for our VoIP network I'd like to configure so that it takes PSTN calls and forwards them to the proper GW for termination. However this is a 3rd paty GW over which we have no control. I've setup the ser to use rewritehostport("host", "port"); in order to send the call to the PSTN-GW but the call fails every time with a 404 Not found This i reported back by the PSTN GW. I belive this is due to the fact that the <To> field contains our realm but the remote GW cannot process it. Any idea how I can get ser to work with this? Has any one setup something similar? Any help would be appreciated, Alex.
