[asterisk-users] Listen on 2 of 3 IP addresses

[Thomas Ray]

The answer is to use chan_pjsip since chan_sip is all but dead, unsupported and going away in v21. Instead of making chan_sip listen on all IPs then making a bunch of firewall/filtering rules that block one of them from being used, use chan_pjsip. It is the right solution as it is the supported driver and will continue to see updates and bugfixes.

If you haven't started a migration from chan_sip to chan_pjsip yet, it is best advised to make a migration plan and do it now. If there is a case where something in chan_sip hasn't made it into chan_pjsip (or it did but hasn't been really touched/updated since) and you really need that functionality, now is the time to figure that out.

    Well...
    maybe chan_sip cannot, but your OS can restrict traffic on any port/iface.
