Unable to make outgoing calls on Tandberg E20

[CSCO10957882]

Dear All,

Will be gratefull if someone could help us in getting a solution.

We  have Tandberg E20 registered (as third-party device advanced) to CUCM  7.0. We are able to make calls to E20 from any SIP or SCCP Phones. But  we are unable to make calls from E20.

Can anyone pls help me on this....

Hi,

As far as I aware, E20 CUCM Integration is not supported yet. You need VCS. You would not see E20 sending its caller ID information (Empty From and Contact headers) and causes Call Manager to reject the call.

E20 Native registration is supported from CUCM version 8.5 and onwards.

Regards,

Vinay
