Problem with DTMF Disables on Credit Card Calls

[RoyRCDD]

Has anyone experienced a problem with subscribers using their DTMF pad to access credit card accounts? I have a problem with these transactions.
When trying to access credit card account information the call goes through but after entering the 16 digit credit card number at the prompt the CS-1000E is not passing the additional DTMF tones for the PIN number. It appears the DTMF is being disabled after sending 16 additional digits.
CS-1000E, Release 5 with IP-1140 phones.

I seem to remember the issue is whether end-to-end signaling (EES) is enabled or not. Wish I could help.

Thanks. But, one of our 'super-techs' with the Air National Guard solved the problem. It was the PRI setups the local and LD trunks. The 'end of dial timers' were set for the factory default; which for some reason is too short to support the time required for long credit card DTMF transactions. The 1024ms setting was found to work, but testing is still in progress.

It is the EOD and ODT timers in the route your tech changed. Setting those to 1024 or even 512 will fix it.

There is little down side. When the timer is too high, CDR captures subsequent, often unwanted digits, and sometimes one party will not be able to hear the other.

If the timer is set very low, then CDR will not always captured the full dialed number on slow poke dialers.

'ah so' said the weary technician with a tear in his eye.
