Hello Stefan, Thanks for the info in the reply below. Apologies for sending the debug dump attached to the email. Wasn't aware that I should have used pastebin. I took your advice and upgraded to the Ser 2.0 rc1 and Sems 1.0.0. I could not figure out how to get the voicemail app to work without the Ser to add the email address. Maybe I just don't understand everything well enough yet. This is ok because I think I would prefer this configuration for scalability. You were right to suspect a NAT, the RTP was expected on a private ip address which could not be reachable by my client. I finally made this correlation when I started the sems server and the 'local media IP' was set to a non-routeable ip. So to fix this, in the sems.conf file there is a parameter called media_ip which should be set to the ip_addr or nic device the sems will use to send and receive media. Setting this parameter did not work for me, however when I added the listen parameter from an older config file I was able to get the RTP streamed media via the public ip address. Is the media_ip parameter suppose to work? If I've done something wrong please let me know? Thanks for your help.

First indicator in the sems debug output is after the AmSession::SipRequest->onSessionStart I'm getting a "posting AmAudioEvent::noAudio event". Additionally when the sendMailNotification is called the log shows that the record size is 0. I'm expecting the recorded voice file to be in /tmp/<sessionid>.wav, but I'm not seeing the file show up. I've started to trace the code, but I sincerely believe that there is some that I have configured wrong. I have included the configuration files and debug output to assist in clarifying what I have stated. Can you help me get the right configuration so that I can successfully record a message and send it via email? Thanks in advance. > > -Randy About passing of parameters to SEMS, you will find string composition much simpler with ser 2.1 functions. As you already have noticed SEMS did not record any audio: (4373) DEBUG: sendMailNotification (AnswerMachine.cpp:343): recorded data size: 0 I suppose you are behind a NAT and your client sends RTP to some public address, thus it does not reach the voicemail server. SEMS expects RTP from 10.x.x.228/43436 . If you run tcpdump, do you see RTP flowing to SEMS? The AmAudioEvent::noAudio is sent to notify the application of the end of the welcome message, so that it knows it should start recording. I would also suggest trying SEMS 1.0 or 1.1 RC1 as it is way easier to use (no need for SER as SIP stack any more etc), http://ftp.iptel.org/pub/sems/1.1/rc1/src/sems-1.1.0-rc1.tar.gz BR Stefan Sayer -------- Original Message -------- Subject: Forward of moderated message Date: Mon, 15 Dec 2008 15:47:27 +0100 From: [email protected] To: [email protected] -- Stefan Sayer VoIP Services [email protected] www.iptego.com IPTEGO GmbH Am Borsigturm 40 13507 Berlin Germany Amtsgericht Charlottenburg, HRB 101010 Geschaeftsfuehrer: Alexander Hoffmann _____ avast!
