Summary:                    Calls get disconnected during a conversation
Description: 
We have several Snom Hardphones on Asterisk 1.2.19, sometimes during a call
(external/internal) it breaks up with following Warning in the Asterisk
CLI:

WARNING[18252] chan_sip.c: Maximum retries exceeded on transmission
3d2cca1cf1b3-c6cbjoxi8rvb at snom320-00041324A7FD for seqno 2 (Critical
Response)

It looks like chan_sip is not processing the 200 OK in response to a
NOTIFY... basically a blind transfer happened and the NOTIFY is sent out to
say "hey everything went fine"... the Snom sends back a 200 OK to
acknowledge receipt of the NOTIFY and chan_sip ignores it.

Can you turn on debug in logger.conf, do a set debug 9 on the console, and
recreate it? It should say why chan_sip is ignoring the packet.
