[asterisk-users] Call ends when picked up

[jonas kellens]

I have set SIP debug on but it is too much output to post on the
mailinglist. I have tried to understand the SIP-messages between my
Grandstream and my Asterisk-server and my Asterisk server and the ITSP.
This is some output that's a bit shorter :

debug log :

[Dec 27 12:11:32] DEBUG[14035] chan_sip.c: Oooh, we need to change our
audio formats since our peer supports only 0x2 (gsm) and not 0x8 (alaw)

messages log :

[Dec 27 12:11:32] NOTICE[14035] chan_sip.c: Failed to authenticate on
INVITE to '<sip:09277xxx7 at ip-ITSP>;tag=as4ca755d8'


Is it normal that I am able to call out ? Making calls is not a problem
at all. There is also codec negotiation there, huh ?!

Also : when I do not use the SIP proxy, receiving calls is not a
problem. I just open up a range of SIP and RTP ports and forward these
to the subnet my IP-phone is on.

As I read your reactions, it seems not to be my SIP proxy ? I doubt that
the SIP-proxy influences the codec negotiation.

This some output of "sip show peer my-grandstream" :

SIP Options  : (none)
  Codecs       : 0xa (gsm|alaw)
  Codec Order  : (alaw:20,gsm:20)
  Auto-Framing:  No 
  Status       : OK (43 ms)

In my Grandstream I have the codecs : alaw - gsm (in that order)
