[Spce-user] RTP bridge and IP in SDP

Hi all

I'm trying to force SIP and RTP to use a different eth/ip for a peer. What I
did:

- In network.yml I added rtp_int to iface eth0 (default is eth2 rtp_ext with
  public IP)

- In config.yml added extra_socket for signaling

- In the panel set rtp_interface to "int"

- In the panel set outbound_socket to the extra one


What I get:


111.111.111.111 -> PUBLIC_IP
INVITE
o=UserA 4007586233 130838284 IN IP4 222.222.222.222'
s=Session SDP'
c=IN IP4 222.222.222.222'


PRIVATE_IP -> PEER_IP
INVITE
o=UserA 4007586233 130838284 IN IP4 222.222.222.222'
s=Session SDP'
c=IN IP4 111.111.111.111'


So, the IP of the proxy is not set in the SDP. No rtpproxy is forced.

Checking the proxy logs:

rtpp_function_call(): no available proxies

No other mentions to rtp in the call log. 

ideas, please? What am I doing wrong?


cheers,

Jon
