[asterisk-dev] Issue 14511

I was going to post a reply to the thread, but can't seem to figure
out how to re-open it once it has been closed.

Either way, I think there maybe a problem related to the codecs issue
that was reported in the issue.

If I see the following:

sip.conf
---
[general]
disallow=all

[authentication]

[hound]
host=hound
type=peer
transport=tcp,udp
promiscredir=yes
qualify=yes
allow=ulaw
---

We get the follow errors "sip_call: No audio format found to offer"

However if we modify sip.conf to the following:
[general]
disallow=all
allow=ulaw

[authentication]

[hound]
host=hound
type=peer
transport=tcp,udp
promiscredir=yes
qualify=yes
---

The error goes away.

The one thing I did notice when we seen the error was the following in the logs.
