I have an asterisk box at home setup on my home POTS line which is working great. Recently I purchased a Sipura SPA-1001 box for use elsewhere, which also works great with my broadvoice account. Today, I decided to configure the SPA-1001 to receive calls from my asterisk box.
Here is where my troubles begin:
The SPA-1001 is registering with asterisk just fine. In fact I can dial it and it rings. Unfortunately, after the call is initiated, no audio is transmitted in either direction.
I am guessing this is due to the fact that both machines are setup with NAT and have private IP addresses. Both configured to route ports 5060-5063 and 10000-20000 to the correct machines.
In the SIP configuration on asterisk (in the context for the SPA-1001) I have:
In the configuration of the SPA-1001 I have:
NAT Mapping Enabled and NAT Keep Alive Enabled
In the advanced screen of the SPA-1001 there are options relating to VIA and STUN which I am unfamiliar with but after experimenting with them I still have the same issues.
Any advice would be greatly appreciated!
