[asterisk-users] Call drop weirdness

[Brett Lehrer]

> I'm running Asterisk 10.7.0 with three sip trunks to my call termination provider. For the most part everything works great.

I'm not sure if this is any help, but I had a familiar issue to this, except it involved transferring to another internal extension.
The symptoms were the same though.  Only outbound audio would cut out and it was very sporadic (~10% of transfers).

The issue ended up being with the trunking service and their spotty support with UPDATE messages.  We had to disable
rpid_update in sip.conf and a couple other bits that I can't offhand remember.  I'd check with the trunk provider on the issue.

Best of luck,
