[cisco-voip] Sip trunking and DR

[Haas, Neal]

We are converting from PRI to SIP, we will have PUB, SUB1 at 1 site and a SUB2 at another site 5 miles away.

With SIP if our main location fails 100% of our DID's will failover to the alternate site.

Our SIP pipe is Voice only.

Hi

I wonder if anyone can help, I'm in the process of speccing out an upgrade of our system and am looking at DR and how we can manage this, specifically in terms of off site Voip kit and how we manage calls going to this site in the event of our main site not being contactable, we use a geographic number so want to keep this and we are currently using ISDN to connect to BT. The main issue I have is over ISDN, if we choose to divert calls our range of numbers diverts down to 1 number with no direct dial functionality.

My questions are:

Is anyone using Sip trunking from a SIP provider for their lines instead of ISDN, and what is your setup (do you have a dedicated pipe for voice traffic, etc)

If you are using ISDN lines how do you do DR and failover if the main site is not contactable?

Are you doing something else?

Thanks in advance

Matt Richards
