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.
