[asterisk-users] DTMF Tone Not Passing Help

[Nitesh Divecha]

Hello All,

Can anyone help me with this DTMF tone problem.

I am running Asterisk 1.2.9.1 svn with couple of Polycom and Snom  
phones.

None of the phones are passing the DTMF tones to remote IVR.

Called 1-800-FLOWERS, when asked to press 1, none of the phones were  
able to transmit the digit.

Can anyone please guide me to correct path on how to solve this problem.

Thanks,
Nitesh
