IP500 Sip fail over

[anthonymo]

I'm trying to configure my IP500 to connect to one Sip provider via 2 interfaces.


IP500 Lan2 ----> PRI to provider
Lan1 -->Sonicwall --> Seperate provider Wireless

I can get two different SIP trunks one set to Lan1 and one set to Lan2 (under network connection) to connect via each connection, however once I unplug Lan 2 it all crashes until I fool around with my IProutes.

I would like a seamless fail over,
Can anyone provide me with a same IP route or two that would make that happen?

Use ARS

If it ain't dutch it ain't much

I will defintly be using ARS once I get the SIP trunks going out over seperate intrefaces so that if one network connection goes down the other takes over.

However ARS is useless if the neither SIP trunk works when one interface fails.

Does anyone have two internet providers hooked upto one ip500 going to one SIP endpoint?

A design problem on your end.

Why would you connect PRI to LAN2?

Ugg I meant a data T1 not a PRI I guess.
Here look at this diagram:

For outgoing you would separate the trunks by trunk group number. Each SIP trunk gets its own outgoing trunk group number.
In ARS you build two tables. One for each SIP trunk group with all entries necessary.
In each ARS / Alternate Route you select the other trunk group number.
If one trunk goes down its ARS determined that no trunks are available and uses the trunk group defined in Alternate Route
