[Asterisk-Users] Dropping incompatible voice frame

[Ben Merrills]

I keep getting console messages like the following:

Nov 17 11:22:33 NOTICE[16767]: channel.c:1320 ast_read: Dropping
incompatible voice frame on SIP/sipuser-5240 of format ALAW since our
native format has changed to ULAW

I think this is causing some incoming queue calls to ring on an agents
extension, however when they pick up the phone, no one is there and the
caller gets taken off onhold music, however they are still shown in the
queue (show queues).

Sometimes, after maybe 30 seconds the caller is bridged to the agent,
and sometimes the channel is dropped.

Anyone know why this might be happening?

All SIP phones are registered to use ULAW.

Cheers,

Ben Merrills
