SIP Server Dialplan Failover

[bfancy]

Hi All,
We are going live with a new site and we are looking at an issue with our SIP server dial plan during failover.

Sunny day dialing everything works fine we can dial between sites all is good.
In each site, we have an include-dial-plan-rule for interoffice where we have entries for the other locations extension range (555XXXX=>009${​​​​​DIGITS}​​​​​) in which we add the trunk code to route the call over.  This works perfectly.

During a failover scenario we have DNs mirrored in each locations SIP server, this also works seamlessly, however the issue becomes that when we do the failover, the site that has failed over is now registered on the local switch but the dialplan still tries to route calls across the trunk and fails.
    Example:  Location 1 fails to Location 2.. Location 2 DNs now registered on Location 1 SIP switch, but they are not able to dial Location 2 extensions, however Location 2 can still dial Location 1 without issue...

Appreciate any assistance.

Regards,

have you tried something like setting on the extensions TServer\dr-forward = no-agent?

From the manual:
no-agent: SIP Server forwards the call to its DR peer when there is no agent logged into the DN.

Thanks no have not tried that.  Will give it a shot and advise.
