Summary:                    * Sends 403 Unauthorized upon reception of INFO
method from  a Nortel MCS 5200 sip proxy
Description: 
The Nortel sip proxy sends an INFO packet every 6-10 minutes and Asterisk
seems not to know what to do with it and replies "403 Unauthorized" instead
of "200 OK" to it. Then the sip proxy still waits 30 seconds for a "200 OK"
and then Hangup the call. 

While the sip proxy waits for it's timeout to finish, it sends again a few
INFO packets which asterisk answers by a "200 OK" but that doesn't make the
sip proxy happy.

Here is the sip logs starting from the first INFO which is instantly
answered by asterisk with a 403 Unauthorized.

If an INFO request within a dialog is received with a content length of 0
simply send back a 200 OK. It is valid to do this and the remote side is
probably using it to make sure the signalling is still alive.
