At my place of employment, we operate with 2 asterisk servers in two different locations, harrisburg, PA and Philadelphia, PA. They are connected via IAX, over a T1. Every now and then, the harrisburg box will stop receiving the IAX packets, ‘iax2 debug’ just shows POKE, no pong or ack, however the philly box shows POKE,PONG and ACK. Has anyone ever had this problem before?
We worked with a vendor and they couldn’t figure it out either.
The only remedy is to change the ports IAX uses on both boxes.
