[Kamailio-Devel] [tm] t_lookupOriginalT : cannot find matching INVITE for CANCEL because of display name

[Aurelien Grimaud]

Hi,
it seems that I have a problem with finding initial INVITE when request 
is CANCELED.
sipp uac (192.168.160.141:5064) contact a uas (192.168.160.23:6075) 
through kamailio 1.4.3 (192.168.160.141:5060)

The request is CANCELED by uac.
But From field is taken from 180 reply and is trhough slightly different 
from initial one.
The display name is quoted and whitespace is missing.

This makes the t_lookupOriginalT fails .... attached log from kamailio 
(check the end)
