I am having some issue with a SIP IVR dialer detecting voicemail terminate tone, the BEEP sound.
It works perfectly on most of service provider's VM system and can detect the beep as beginning of VM without problem. However for a specific mobile phone SP in Canada, their VM tone is different from others, and you can easily tell the difference by hearing them. In this case Dialer cannot detect it.
I have a TAC opened. I am just wondering if anyone here would have a suggestion or workaround?
So far I have tried couple things but Cisco dialer really does not provide too many options on this specific feature. I have tried disabling the terminate tone detection and that made some calls even worse.
Another big issue related to this, and more or less appears to be a bug to me is: when Dialer detects VM but could not detect terminate tone, it will not leave a message in the VM however still closes that dialer records with result of "12", which is Voicemail.

Yes, it had been confirmed by Cisco as bug and a DSP firmware ES was released to this customer. I was also advised by Cisco that this ES will be rolled into 15.1(3)T4, targeted for CCO availability on 6/5/12.
Hi, I thought I had sent you the DSP firmware on Feb 17,2012 to firstname.lastname@example.org. It did not work for you? That would be the firmware fixed our problem. Anyhow, the case number is SR 620068785, you may want to follow up with TAC.
