IAX2 code compatibility btw 1.8.2 and 1.8.3


Got a major problem. Every time I try to upgrade a server, I get something like this:
[Mar 30 07:50:53] NOTICE[10453]: chan_iax2.c:10958 socket_process: Rejected connect attempt from, requested/capability ‘0x400000000000000 (nothing)’/‘0x600000000000000 (nothing)’ incompatible with our capability ‘0x4 (ulaw)’.

This only happens when one side is 1.8.3.x and the other is 1.8.2.x. If I downgrade again, all is well.

I am concerned because I am connected to * servers I have no control over as to their version number. I could upgrade all of mine, but external connections might then be severed.

Any thoughts?
