Set up broadband fail over for IP authenticated Sip trunk

Hi,

We have two broadband connections both connected to our Draytek 2850 and we have a Sip trunk authenticated by one of our broadband IP address connected to our PBX. The Sip trunk is provided by Gamma telecoms and only one IP at a time can be set for authentication (or so I've been told).

My question is, when WAN 1 fails the Draytek will auto fail over to WAN 2, our internet continues to work, however our Sip trunk is not authenticated on WAN 2's IP address and does not seem to work.  

How can this be set up, or if not then what is a reasonable alternative?

Any questions please ask.

Regards

Have you checked with the Draytek support? I don't think Draytek 2850 supports sip trunk failover!

For authentication I think you will need to talk to your ITSP to authenticate both IPs in case of SIP trunk failover scenario.

Hi,

Thank you for your response, the Sip trunks sit on the broadband and the Draytek supports broadband fail over, I'm not sure if it needs to take into account the Sip trunk?  

I have been told by the Sip trunk provider that only 1 IP address at a time can be authenticated, so unless this is not true then I guess there might be a way to mask the IP?

I guess the question should have been, how do you set up redundancy on a sip trunk?

Thanks for your help, I've looked into it further and there are plenty of routers on the market that will stay up if one WAN fails and in some cases a voice over IP call and SIP line will continue to work.  I believe that this just comes down to the SIP supplier making their SIP trunks IP authenticated, I will either have to speak to them in the hope they have an alternative or just find a different supplier that doesn't IP authenticate, which I have already done (Sipgate).

So thanks for your help, cheers.
