Hi,
I think the choppy sound problem with Cisco 7940/7960 through IAX is back... at least when trunk is enabled.
The old issue was: http://lists.digium.com/pipermail/asterisk-users/2004-April/043280.html
Diagram of the network:
Cisco 7940 -> SIP G.711U -> Asterisk A -> IAX G.729 -> Asterisk B -> X100P -> PSTN
With trunk=yes audio to Cisco is choppy. With trunk=no the problem disappears.
I tried several combinations of G.711U and G.729 in the SIP and IAX links but the problem remains.
Tried calling serveral Asterisk servers (Asterisk A -> Asterisk C, Asterisk A -> Asterisk D) and the same problem occurs so it's not specific between this 2 Asterisk servers.
This only happens with Cisco 7940. Switching 7940 for an Grandstream BT100, Cisco 7905, Avaya 4602, Digium IAXy, Snom 105 or X-Pro the problem disappears.
I don't have other Cisco 7940 unit to test but since it make SIP->SIP and SIP->ZAP calls with no problem i think the problem is not on the device itself.
One difference from the old issue is that the firmware of the Cisco is not 6.x, it's 7.x (POS3-07-2-00).
Both Asterisk servers running 1.0.1 release.
Any ideas ?
Is there any test or debbuging i can post to help ?
Thanks,
Leonardo
