[cisco-voip] Unity Failover and PIMG Integration question

[Zachary Gillman (US)]

Greetings all,

 

We have a customer that has implemented Unity 4.2 with a failover
server.

They have an IP integration to CallManager and 2 PIMGs to a Nortel
Meridian.

 

Here is the scenario, the failover monitor will initiate a failover when
any of the AV services go down or there is a full server failure, that's
how it was designed to work and is doing its job.  The PIMGs will only
home to the second Unity Server only if there is a full server failure
and connectivity has been lost, it has no visibility to the AV services.
So if there is a software failover, the PIMG will still see the Primary
Unity Server in service and route the Nortel voicemail calls to the
Primary Unity server, that's how it was designed to work and is doing
its job.  

 

In the Cisco PIMG with Nortel Integration Guide, it instructs you to
check the "Failover if a call arrives on an inactive secondary server"
within the failover monitor.  That seems somewhat odd since the scenario
depicted above breaks the Nortel voicemail routing if there is a
software failover.  

 

Has anyone had any support issues with regards to unchecking this
option?  The customer would rather get a busy if the ports are maxed
out, but is concerned that if they go against the guide, Cisco will not
support it.

 

Thank you in advance for your time and help.

 

Zack
