Hi to all,
I’ve successfully connected 2 pbx each other by IAX2 trunks:
freepbx*CLI> iax2 show peers
Name/Username Host Mask Port Status Description
System2/System1 151.xxx.xxx.xxx (S) 255.255.255.255 4569 (T) (E) OK (8 ms)
1 iax2 peers [1 online, 0 offline, 0 unmonitored]
When I try to call an extension of pbx-a from pbx-b the extension rings, the call begins but I’ve no audio between. If I view asterisk console I can view this warning after call terminate.
