I'm making a wild guess here, but I'd say that if you're using
trunking, then you're probably getting close to exceeding the MTU size
or possibly the MAX_TRUNKDATA size as defined in chan_iax2.c.  If it's
happening without IAX2 trunking turned on, then I have no idea what's
happening... you'd have to look at the IAX2 and SIP packets when the
problem is happening, and try to figure out what's causing the issue.
