Call Forward All to VM getting delay

[cnorton]

Hi Guys,

Good day! Hope everyone is doing well at the moment. We are having some weird issue with our callmanager and unity connection. They both on version 8.x. Whats happening is that when a call for an extension is forwarded to voicemail (tick VM under Call Forward and Call Pickup Settings), we'll get a 10 second delay in getting response from the cisco unity and instead hear 2x rings. After that, we'll then get the user voicemail greeting. It works fine when we point it to another unity cluster, wherein we get immediate greetings instead of 2 rings. That proves that the issue lies on the cisco unity server but we dont know what settings dictates this kind of behavior. Please see debug isdn q931 sample

Hope somebody can help us with this. Please advise if additional sample/tests are needed for this. Thanks!

Hi,

Look for the user under Cisco Unity Connection Administration -> Users.  Click on the user and look under those particular user's settings.  Do this by going under Edit -> Transfer Option.  There you will find under the option that is enabled whether the Transfer Action is Release to Swtich or Supervised  Transfer.

Supervised Transfer has a setting that indicates Rings to Wait for. It is possible that you are set up for Supervise Transfer to voicemail and this is the reason for the additional rings.

Hi mgogna,

Thanks for your reply. I checked the user settings and their transfer type is set to release to switch instead of supervise transfer. Also, voicemail greeting is set to "Take Message" therefor transfer rule will not be applied.
