[SR-Users] Kamailio inserting Quote " mark in SIP header

[Arslan Saeed]

Hi All,

We are seeing that Kamailio's nat_helper_module function of
add_rcv_param(),  inserts " (quote)  mark to some of the SIP headers (as
below in the contact header in sip 200 OK response)


Contact: <sip:172.70.1.2:5060;bnc;received="sip:118.107.184.242:25090
">;expires=172


We got few SIP UAs that are  complaining about the quote mark inclusion in
contact header and responding back with SIP 400 bad syntax status code.


Requesting views / suggestions from community about this behavior of
kamailio and any workarounds available.

Cheers
Arslan
