DTMF For Long Distance Carrier Code

I am testing the Yealink T48G with firmware versions and

Calls to PSTN are routed from S4B through Sonus SBC1000 then to AT&T PRI circuits.

Long distance calls require a Long Distance PIN Code from AT&T.

When greeting with the prompt for PIN Code, pressing the number keys on the T48G generate no tone and the long distance call can not be placed.

DTMF tones work with all other IVR systems. The DTMF only fails with AT&T long distance pin code.

Recap: DTMF is not audible for AT&T Long Distance PIN Code but works everywhere else.

Side note: We are also testing the T46G and we can hear the DTMF tones when prompted for AT&T Long Distance PIN with the T46G. However, the PIN code still does not work with the T46G even though it can be heard.

We are testing these for a 1000 user S4B environment and this is hanging us up from purchasing.
