I had the same problem ,  don't remember how I resolved it. What is your
dial-peer and sip settings on AS5300? I will compare it to mine for any
difference.

I had the same problem and I believe it was the payload size of the
codec.  What code are you using?

I get this error message when sending calls to a Cisco Gateway AS 5300,
one
call out of 10. Is there any configuration hack either on Asterisk or
the
Cisco that would this problem go away??
