[cisco-voip] Unity connection - Voicemail playback

[Ryan Huff]

Nate,

Admittedly, not very clear. 

The design strategy I'm referring to is with the use of Digital Networking (http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/srnd/collab10/collab10/vmessage.html). The intent wasn't to suggest that you could add ad 3rd node to a 2 node CUC cluster.

The reason I didn't suggest forcing a failover in CUC serviceability is because I have seen it cause issues with the IVR, where the conversation service needs restarted on the nodes. 

My recommendation for dropping the ports out of the line group was to avoid potential issues with CUC.


Thanks,

Ryan

Ryan, When did CUC start to allow more than two nodes in a cluster? Jose, You can go into the unity connection serviceability and click “stop taking calls”  Then there are no configuration changes to deal with, just turn it back on when the link is stable. -Nate From: cisco-voip [mailto:cisco-voip-bounces at puck.nether.net] On Behalf Of Ryan Huff

If SIP integrated, easy fix, just point the trunk at the pub (and then reset the trunk in CUCM).

If SCCP integrated, you have a few different options and the best option depends on how you're setup and if this is a perm. change or just temporary?

If this is just temporary and assuming you have the max amount of ports per CUC node, In CUCM I would go to the line group of the SCCP ports and drop out the ports that are registered to the CUC subscriber node. Once your link is no longer saturated, add the ports back to the line group.

There are some other design strategies that you can look at to help mitigate this in the future. For example, you could add an additional CUC Subscriber node in the same DC as the publisher (so you end up with a subscriber in both data centers). This would allow you to have additional ports in the same DC as the publisher.

You have to change the priority of the trunk or the ports so it uses the Sub first. +ChrisTME - Unity Connection and MediaSense From: cisco-voip [mailto:cisco-voip-bounces at puck.nether.net] On Behalf Of Jose Colon II

Subject: [cisco-voip] Unity connection - Voicemail playback I have a Unity 10.5 HA setup and the subscriber is at our COLO. Currently the link between the two is being saturated so voicemail playback is very choppy.  The question is, how do i force the publisher to handle those requests so that voicemail playback is handled inside this location and not at the colo? ThanksJose
