[Serusers] busy indicator
by Richard 25 May '04

25 May '04

Hi, In traditional PBX, there is a feature to indicate if another user (more precisely his phone) is being used or not. This would help before transfering a call. Is there a way to support this in ser? If record-route is used, ser knows that users are on the phone bewteen ACK and BYE methods. Is possible somehow tell other phones about the status?

[Serusers] Problem registering ATA 186 with authentication.
by Pablo Bertuzzi 24 May '04

24 May '04

Hello guys Could anyone register an ATA 186 with sip version v.3.1.0 to ser using authentication? I am running ser v0.8.12 on a RH9 machine. All equipments has public IPs. I configured the following parameters in the ATA: UID0:1000 PWD0:(the pass configured in ser) GkOrProxy:(ip address of ser) UseLoginID:1 LoginID0:1000@myrealm.com (where myrealm.com is the realm configured in ser) SIPRegOn:1 When ATA sends a REGISTER ser responds with 483 to many hops. So ATA does not register to ser. I tried the same user with Windows Messenger 5.0 and ser responds with 401 unauthorized user and the nuance, so MSN sends the new REGISTER with all the information. Finally MSN does register to ser. Any help on this matter is appreciated. Pablo.

[Serusers] invites timeout after period of time
by Harold Workman 24 May '04

24 May '04

hi, When I load X-Lite behind a Single Mapped Port Symmetric NAT Firewall and make a call to it, the X-Lite rings and I can hear voice in both directions. The problem is when I leave the X-Lite sitting idle for over 1 minute, the inbound calls to client start to time out. Outbound calls from client work no problem. Im not receiving anything on the X-Lite debugs, and when i debug the SER, I see repeatedly sending Invites with no response. Below is the debug...64.72.107.2 is my Gateway, .4 is my SER, and .1 is my firewall NAT address where my client X-Lite sits behind. If i close the X-Lite and open it back up, I am able to make calls to it again until I leave it sit idle...Any ideas? Could something be wrong with my nathelper? Failed Attempt...

[Serusers] ser and mediaproxy
by Tjapko ITS Consult＠ncy 24 May '04

24 May '04

Hello list, I am new to SER and have a question about NAT penetration in general. All parts of SER and mediaproxy are running fine but I am still am struggling a bit with NAT penetration. According the readme for Mediaproxy ser module any endpoint that is behind NAT needs to configured with outbound proxy enabled. Are there any examples available how to do this when using mediaproxy. This way the nat penetration is not likely to be really transparent but needs a configuration issue on the EP. Can anybody confirm me this please or hint me to reading material on this subject.

[Serusers] doubts on rtpproxy working properly - obviously a versioning problem
by Franz Edler 24 May '04

24 May '04

Hi all, sorry for bothering you with my rtpproxy problem again. I now looked for a potential error output of rtpproxy and found: "rtpproxy: command syntax error" whenever force_rtp_proxy is called. In addition I found a comment from Jan Janak in the mail-archive on a similar problem (ser together with rtpproxy): "My guess is that you are using incompatible versions of rtpproxy and ser, as far as I know the rtpproxy from cvs can be used with unstable only." That's obviously my case. I am using stable ser 0.8.12. Therefore I have to switch to unstable ser and try again. Greetings Franz
