Hi,
I am working on a PBX topology that’s probably very uncommon.
We are a service provider, who are testing SIP trunks with Asterisk. So for now, we are using an SBC to send a trunk (public/client-realm) to the Asterisk PBX and connect through the SBC to the MGC on its private-realm.
Basically:
- SBC Trunk/Asterisk-Server is on : 172.1.10.x/24
- SIP phones: 172.1.11.x/24
- Public IP: 213.x.x.x/30
All interfaces are routed through a cisco router.
Question is, in such a scenario, would it be possible to:
- Configure SIP clients/users from the internet?
- TO connect SIP clients from the internet, would configuring port-forwarding on the cisco router alone (from public-ip 213.x.x.x/30:5060 -> 172.1.10.x/24:5060) be enough to register with the asterisk Server?
I’d like to hear your thoughts on whether this is doable or/and if anyone has experimented with something similar.
thanks.
