[Asterisk-Users] SIP INVITE with no 'Contact' field and RealTime support.

[lokotes]

Hi,
When sip device sends to Asterisk INVITE with no 'Contact' field, the 
server should respond with all information it holds about client. When 
reading database fields, 'fullcontact' is empty. So, whole procedure 
ends with 'chan_sip.c:6393 register_verify: Failed to parse contact 
info'. Interesting thing, internal database (CLI> databse show 
SIP/Registry xxxxx) holds all valid information about this client, so 
why it's not used?
