Hello,

 

I have an issue about ringing back tone when I call from outside --> PSTN (SIP trunk) --> CUBE --> UCCX --> redirect call to extension. I hear IVR and can do DTMF. then press extension, no ringing back tone.

However when I call from PSTN (SIP trunk) --> CUBE --> DID (direct to IP Phone). I heard ringing back tone.

Call from inside to outside, I heard ringing back tone.

 

I connect cucm to cube by create H.323 gateway.

 

cucm 10.x

uccx 10.x

cube (cisco 2901) Version 15.2(4)M5

 

Please help

Thank you

Dear Frank,

 

Thank you for your suggest. I did what you link to me however, it did not work either.

If you have any more information, please let me know

Hello Was this every resolved?

Can you try changing theg Service Parameter"Send H225 User Info Msg" parameter and set it to "Use ANN for ringback" and see if it helps pls?

Also make sure you have Annunciators registered and available in the MRGL assigned to H.323 Gateway.

It is clusterwide parameter and hence applies to all node in the cluster.
