[Asterisk-Users] Inbound SIP DTMF detection

[Paul Cheng]

Hi,

We have our * box configured to receive inbound SIP calls from FWD and 
enter into an autoattendant where someone can enter an extension 
directly.

However, the inbound DTMF is not being correctly detected in most 
cases. Entering 8050 results in a correct detection, but enter 9003 
results in only 90 being detected. Entering 700 results in 70 being 
detected. 799=79, etc.

It appears that repeated digits do not get detected. 8750 works, but 
999 results in only 9 being detected.

Has anyone else experienced this problem? We are using X-lite as the 
client on the FWD side to test.
