DTMF tones don't work in CUE voicemail but work in automated attendant

Unanswered Question

I am running CCME and CUE; an outside caller can call in and enter an extension and DTMF tones work just fine, but the problem I am having is but when the caller is transferred to the CUE mailbox, DTMF tones do not work. Additionally, DTMF tones work fine for any internal callers accessing voicemail. I suspect they are somehow lost in the transfer between the automated attendant and the last called extensions mailbox. It's like CCME does not know how to match up the tones to the correct extension. Any tips on how to troubleshoot are appreciated.

I would remove

voice-class codec 1

voice-class sip dtmf-relay force rtp-nte


and just use

codec g711ulaw

dtmf-relay sip-notify


CUE only speaks g711ulaw anyway, no need to try to elegantly allow for other codecs. Also every technote I have ever seen uses SIP notify DTMF for CUE.

Thanks for the info, I have implemented the two recommended changes, however, this does not change the results. My voice-class codec 1 only consisted of one codec, g711ulaw; so there was really no change there.
