Summary:                    Calls drop due to unanswered INVITES
Description: 
Calls with a MetaSwitch (or any device which uses INVITE to check for
remote existence) will drop with Asterisk 1.4.18 when the 200/OK send as a
response to the INVITE is lost.

I've fixed this by sending my 200/OKs as CRITICAL during the handling of a
reinvite (an easy modification in chan_sip.c)

Ultimately, it might make sense for this to be a setting in the sip.conf
(handle reinvites critically)

200 OKs in response to a reinvite need to be sent reliably. If the remote
side does not receive one the dialog will be torn down.
