[OpenSIPS-Users] parser errors

Hi Jeff,

First error (parsing the TO hdr) means a \" char was present in an 
enclosed URI (<....>)  - form the log, the TO hdr indeed looks bogus..
The second error is related to the first one - when the 400 reply was 
received and opensips tried to parse it, it came across the bogus TO hdr 
-> the parse_headers failed (and parsing of the reply) failed as the TO 
parsing failed.

The fact you see it several time is because probably the sender of this 
400 reply is doing retransmission as no ACK is sent back.
