CUCM - Webex Callback DTMF issue

[juan.anzola]

Hi!

    Im having some trouble with webex conferences. When i use the "Callback" feature, i recieve the call but when it asks to accept it, i press the digits and nothing. its lik a DTMF-relay problem but only fails with the Webex callback feature.

Any Ideas??

Hi Juan,

Did you tried from another device?

You can also take that option off, in the admin side you can disable this feature...

Thanks

Hi,

I meet the same issue when external PSTN try to join the webex (no issue from Internal Cisco Phone).

Did you solve your issue?

Thank you

Best regards

I hope this is the right post for help on my issue. I've added Cisco's WebEx IP as an H.323 endpoint on an MCU 4520. It connects to WebEx, however it does not recognize DTMF when I try to put in the meeting number. 
It works fine with other preprogrammed endpoints, but not WebEx. Ultimately, we usually connect them via SIP address, but if I can make this work it would be nice. 
Any advice would be helpful. Thanks.
