All, Has anybody else experienced garbled voice between a phone using alaw/ulaw and one using iLBC? I have a Nokia E series phone with a preference to use iLBC and this works fine in Asterisk 1.2. However, since moving to 1.4 - I get garbled voice on Inbound (g711->iLBC). Outbound voice seems fine (iLBC->g711) though. It's not a 20/30ms framing issue as the phone uses 30ms frames the same as Asterisk. Interestingly, my Grandstream seems to work well with iLBC though. X-Lite on the other hand often starts fine but sometimes becomes garbled 5+ minutes into a call. Connectivity is over a LAN so should be excellent. The only noticeable difference in the Grandstream vs. Nokia is the Nokia sends 'a=rtpmap:97 iLBC/8000/1' in the SDP info while the GS sends 'a=rtpmap:97 iLBC/8000, a=fmtp:97 mode=30'. I realise I need to provide more info and log a case - but I was wondering if anybody had seen something similar since moving to 1.4 or whether I'm on my own here? Cheers, Ray
I got some Grandstream Gxp2000 v.2 phones and I can get them to make and receive calls but there is no audio? My softphone work fine using the same accounts. Anyone have any idea what could be wrong by just switching in a hard phone vs. softphone? Thanks, John
John, - Make sure you are using the correct codecs, and other SIP settings (ports, dtmf, and the like) - Receive a call, then when you have no audio, press any key on the device. This should restore audio if you are using firmware 1.1.1.14 or lower.
