Hi all,
------------------FREESWITCH--------------(bridge=sofia/external/sip:outbound-opensip.com:5060)-----------OPENSIP----------------------
I am facing NAT problem when i am dialing SIP URI via sip profile. When i am dialing the SIP uri with Gateway trunk NAT is working properly.
Dialing SIP URI
<action application="bridge" data="sofia/external/sip:outbound-opensip.com:5060"
In external profile setting I made the setting for ext-rtp-ip and ext-sip-ip. In freeswitch cli "sofia status profile external" i am able to see the external rtp and sip ip correctly.
But when freeswitch sending INVITE external IPs are not set in SDP and FROM Header, instead it is using local IP. When i tried to debug the problem in switch_core_media.c freeswitch failed to check the NAT settings.
switch_core_media.c
SWITCH_DECLARE(switch_status_t) switch_core_media_choose_port(switch_core_session_t *session, switch_media_type_t type, int force)
/* Check if NAT is detected */ if (!zstr(smh->mparams->remote_ip) && switch_core_media_check_nat(smh, smh->mparams->remote_ip)) { /* Yes, map the port through switch_nat */ /* Code */ } else { /* No NAT traversal required, use the profile's rtp ip */ use_ip = smh->mparams->rtpip; }
Here remote IP is NULL always when i am dialing URI with external profile. When I tried to make call by "sofia/gateway/trunk/sip:outbound-opensip.com:5060" i can see the remote ip as "oubound-opensip.com" and its able to external IP in SDP.
Can any body tell how to solve this problem ? Is there any configuration to set relam in dialplan ?
I am using freeswitch version 1.5.6.
Hopping the earliest response.
Regards
Andrew
