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)
