how to put external ip for freeswitch on freepbx v3 interface?

Hi,
I'm trying this freepbx_v3 but i notice on the interface there seem to be no way to define the public IP on the interface. The server itself has no define public ip but this is define statically on a cisco router. I already have tried this and it work on a plain freeswitch.
So how to put external ip for freeswitch on freepbx v3 interface? The xml generated by freepbx are the following lines, (on ansi character)
@lt:/domains@gt:
@lt:settings@gt:
@lt:param name="rtp-ip" value="10.20.1.22"/@gt:
@lt:param name="sip-ip" value="10.20.1.22"/@gt:
@lt:param name="ext-rtp-ip" value="10.20.1.22"/@gt:
@lt:param name="ext-sip-ip" value="10.20.1.22"/@gt:
@lt:param name="sip-port" value="5060"/@gt:
@lt:param name="auth-calls" value="true"/@gt:
@lt:param name="context" value="context_3"/@gt:
@lt:param name="rtp-timer-name" value="soft"/@gt:
@lt:param name="codec-prefs" value="$${global_codec_prefs}"/@gt:
@lt:param name="inbound-codec-negotiation" value="generous"/@gt:
@lt:param name="nonce-ttl" value="86400"/@gt:
@lt:param name="manage-presence" value="true"/@gt:
@lt:param name="force-register-domain" value="$${domain}"/@gt:
@lt:param name="force-register-db-domain" value="$${domain}"/@gt:
@lt:/settings@gt:
So is there's away freepbx_v3 interface to edit public ip on param name like ext-rtp-ip and ext-sip-ip? Would manually be preserved?



Hey there!
This was a deficiency in the design that has been resolved in RC1. There are now places to add that information.
Remember, because the XML does not get clobbered unless you change something, you can always manually add it to the file.
