No ring back from CCX application or Unity call handler

I set up a new call flow that utilizes option 1, 2, 3, and 0 as input selection from both unity server and CCX application. But there is no ring back on the transfer to target extension. It's just silense until answer or hit voicemail. A normal call direct to extension has ring back ok.

Here is my set up.

Call comes from PSTN ==> CUBE ==> to CUCM through SIP Trunk ==> Unity Call Handler ==> Transfer to extension in CUCM

Call comes from PSTN ==> CUBE ==> to CUCM through SIP Trunk ==> CCX application ==> Redirect call to extension in CUCM

I have searched couple suggestions from this forum but can't find a soultion yet. I also reset Annuciator and reboot CUCM server but no luck neither.

Thanks.

Depending on the type of transfer, you could be using the network hold audio source from either the voicemail ports, or the CTI ports for CCX.

In CCX are you using a Call redirect or call consult transfer?

Anthony,

In CCX, Call Redirect is used. And in Unity I am using the Release to Switch option. I will try the hold option with CTI ports to see if there is any luck.

Thanks.
