I'm hoping someone can give me some more details on the SIP/RTP proxy features of ASG 7. My emails to Astaro have gone unanswered so I'm hoping the community will pick up their slack. Ok. enough intro.
My business currently uses SIPX (a sip based pbx) for VOIP. We will soon be doing a SIP trunk to an external provider for our outbound/inbound calls. However, the SIPX server is behind a NAT/Firewall and moving to a public ip is not possible. For sip to work behind NAT we either need to Port Forward every port under the sun or use a Firewall that has a sip proxy built in.
The Astaro literature states it has a SIP/RTP proxy but the details are slim. Looking at the admin guide also show few details about deployment scenarios. The docs seem to be geared more for a UserAgent (UA) behind the nat connecting to a provider like vonage. Is that the only scenerio that works?
Does anybody have experience with a SIP server behind Astaro? I downloaded the demo and the options are pretty slim. And I'm not seeing the options I would expect from a true SIP/RTP proxy compared to something like the Ingate Siparator. For example, on outbound calls the sip proxy doesn't need much configuration but for inbound connections/registration the SIP proxy needs to know which domain and sip server to forward calls to. I don't see that anywhere in the admin page.
Any help would be appreciated. If astaro works with sip as we will use it replace our current Bordermanager firewall.
Thanks,
Tim
