Hello Everyone,

I am trying to diagnose issue with my IAX2 extension not working.

When I have iax2 set debug on all I see is this:

*Rx-Frame Retry[ No] -- OSeqno: 000 ISeqno: 000 Type: IAX     Subclass:
*   Timestamp: 00003ms  SCall: 00130  DCall: 00000 []*
*   USERNAME        : 100*
*   REFRESH         : 60*
*Rx-Frame Retry[ No] -- OSeqno: 001 ISeqno: 001 Type: IAX     Subclass: ACK
*   Timestamp: 00003ms  SCall: 00130  DCall: 00001 []*

So, all the packets are coming in, but there is no Tx response. Is that
normal and is that how IAX2 works according to RFC to not respond back?

I have checked my firewall and all is set fine. I have any WAN address to
come in through port 4569 to map to the server and it worked last week but
now it doesn't.

Any suggestions?
