[OpenSIPS-Users] cannot parse the Contact URI with colon in display part

[Bastian Schern]

Hi,

IMHO the definition for the display-name of the "Contact" and "From" is 
similar.

Complete SIP message with bad diplay names in header parts:
--- snip ---
REGISTER sip:192.168.100.100 SIP/2.0
Via: SIP/2.0/UDP 192.168.100.177:5060;branch=z9hG4bK-2e2fcbb8

The error message is only announcing the bad "Contact" value. Also the 
REGISTER message is accepted by OpenSIPS correctly.

I have two questions about that:
1. Is the ERROR is only generated by the nat_traversal module?
2. Is it really an ERROR or is it only a WARN or INFO message?
