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
