[OpenSIPS-Users] receive port during call process
Hello! I have a such problem. Opensips using 2 ports One – 5068 for client which must register on Opensips Second – 5060 for all other clients. 1) Client А registering on Opensips (socket: udp:2.2.2.2:5068). Client A is behind NAT. 2) Client А receives incoming call (via lookup() function). 3) Call has such way Cisco (source port 1 sends INVITE to port 5060 of Opensips) – Opensips (receives INVITE from Cisco to port 5060 and sends the INVITE to client from source port 5068 to some client`s port) – Client A. Everything work fine until client А answers. Then Client A sends to Opensips (port 5068) 200 OK, Opensips retransmit it to Cisco (from port 5060 to 1), Cisco sends to Opensips ACK (from port 1 to 5060) AND Opensips retransmit this ACK to client`s port FROM PORT 5060, BUT NOT 5068. This ACK didn`t reach client A because of NAT. Thank you for any help. ___ Users mailing list Users@lists.opensips.org http://lists.opensips.org/cgi-bin/mailman/listinfo/users
Re: [OpenSIPS-Users] receive port during call process
Hi Denis, The ACK is routed based on the RR headers that were collected by INVITE and returned in 200 OK. For such a scenario to work, opensips is doing double routing (adds for itself 2 RR headers, one with the inbound interface, one with the outbound interface). Could you post the SIP capture of such a call to check if correct from SIP point of view? Regards, Bogdan Denis Putyato wrote: Hello! I have a such problem.

Hello, Bogdan!
modparam("rr", "enable_double_rr", 1) helps me. Before this parameter had value
0.
Thank you.

Hi Denis,
The ACK is routed based on the RR headers that were collected by INVITE
and returned in 200 OK. For such a scenario to work, opensips is doing
double routing (adds for itself 2 RR headers, one with the inbound
interface, one with the outbound interface).
Could you post the SIP capture of such a call to check if correct from
SIP point of view?

Bogdan
