I have a Cisco 2800 like a voice GW, making a Trunk SIP with a Asterisk PBX. I don't know the Asterisk configuration. My GW is used only to external calls, using a PRI port. We have problems with calls since 10 days ago: I can make a call but the called can't hear me and I hear him.
The communication between the Asterisk Box and my 2800 is Internet, both have publics IPs, so there's not firewall between them. I should say that my 2800 have been working till now like GW from differents ASterisk's box, and we don't have problems till now, but this "Asterisk's cluster" have differents VoIP GW from differents partner and they use them on demand. We gave them support over our GW only when they have a problem.
So we are checking actually if this Asterisk Box is new or if it's one of the oldes't (from de Asterisk's cluster).
I need some help about this problem. I attach logs with differents debugs from the asterisk pbx.
Asterisk's owner tell me that their asterisk box don't accept g711 codec but I don't think the same looking their traces.
Coud you please help me? I need to know if the asterisk box is misconfigured or if the problem is my cisco 2800 gw (which work with another pbxs).
