Hi:

I have 2 Sip Providers. The first one uses GSM and the second one uses G729; this is the failover for the first.

When first provider fails for "Congestion", the failover trunk tries to use GSM codec instead of G729 and obtains an "Unsupported Media Type" reject message.

When first provider fails because it is "dead", failover trunk works fine.

I do not know if this is an a2billing or an asterisk problem. Perhaps it is missing some instruction to reset the previous call.

I tried canreinvite=no but it didn't solved..

This is some log print

[Dec 25 10:41:18] DEBUG[24435] chan_sip.c: *** Our native formats are 0x100 (g729)
