CME SIP Phone 3905 second dialtone issue

[Australian]

Hi Guys;

I have search on the internet and knows that CME does not support SIP phone for second dial tone about six years ago.

https://supportforums.cisco.com/discussion/10793811/about-secondary-dial-tone-cme

Does it support now?

In my customer site I have configured below command on CME but it doesn't work (customer phone type:  3905 SIP phone)

telephony-service

     secondary-dial digit-string

I have registered my CIPC on CME, the second dial tone works.

Hi Suresh,

Thanks for your reply , Don't know why this feature not available, Lots of my customer are having the same question.

Hi,

Suresh is right, secondary dial tone is not presently supported for any SIP phone registered to CME. If you have a business case you may engage your Cisco Account team for a feature request.
