Hangup on incoming calls

livtrase · August 8, 2007

Hi all,

I have a problem with Axon 1.20 on an XP workstation together with a Linksys SPA-922 as a VOIP hardphone and a Zyxel ATA Prestige 2000 with an analog phone behind.

When using an external trunk to my Voip provider, everything works fine with the outgoing calls as well as the incoming calls to the analog phone (via the Zyxel ATA).

However, when a call comes in via the Voip provider and I pick up the SPA-922 hard phone, I get an immediate hang up. First I thought that this is must be with the UDP ports for RTP on the firewall (my VOIP provider uses 10000-50000). However, the analog phone via the ATA works so that this cannot be.

I generated two SIP trace files - one with the Voip hardphone where it does not work (hang up) and one with the ATA where it does work. See below.

Any hints are much appreciated.

Cheers,

Stefan

I didn't have time to look over your IP trace, but I encountered this problem once. In fact it was with the Zyxel Prestige voip modem you report being the device that works.

Anyway, the problem turned out to be a codec issue, and this is probably the case regardless of the hardware.

IVM only supports the free, open codecs like G711 (alaw / ulaw) and GSM. However some VoIP phones/devices are defaulted to only use certain codecs (such as G729 that are not Axon compatible) or may not be capable of supporting the compatible codecs. For me, I simply changed the setting to use G711 as the main codec and this solved the problem for me.
