[Spce-user] Multiple ports for peer

[Oskar Krigh]

Hi, and thanks for the answers.
The second alternative sounds good, but unfortionatly im not able to add the second peer, since it is the same ip as the first one. I haven’t tried to add it directly into the database, I have just used the GUI for this.
Would it be a GUI question or wont it work to add an extra peer with the same IP?

The First alternative works, but my proxy starts to send out packets on that second port to, and that is not what I want.

Hope for more answers

Hi,

So you want to send traffic to that peer from your local standard port 5060, and receive traffic from that peer on your local port, let's say, 55060? Then you'd just need to add another listen directive in
/etc/ngcp-config/templates/etc/kamailio/kamailio.cfg.tt2 and execute "ngcpcfg apply". Should work.

Or do you actually mean that your local port stays 5060, but you send requests to peer port 5060, but receive it from peer port 55060? Then you need to create two separate peers in your config. Just add the peer with port 55060 (where you receive traffic from, but never send traffic
to) in a separate group, but don't create any peering rules for it (so it's never used for outbound requests).
