External Auto Attendant Not Working

[dekatech]

Hello,

When calling a company who has an automated attendent that asks the caller to input (1 for sales, 2 for customer service etc..), the receiving end is not accepting any key pad input. When disconnecting from the 3cx server and configuring directly to Voip provider (in this case BroadVoice), the call is transmitted and keypad input is accepted successfully.

Is this a bug or a configuration/operator issue?
Any ideas?

Check your IP phone that is sending DTMF "in audio" or otherwise named "in band"

Thanks That Worked. IP 501 Config Info

Changing the following line in the sip.cfg file for the IP501 enabled the IVR to work correctly.

tone.dtmf.rfc2833Control="1"

Change the "1" to "0" and the IP501 should work correctly.

Thanks again for the tip about inband.
