[asterisk-users] Passing DTMF

[Christopher Gray]

Hello:

I need to be able to reliably send out touchtone to any calling party who comes 
into my pbx.  The standard things to help with this have been done as far as I 
know:

1.  dtmfmode is rfc2833.

2.  The phones themselves are set to rfc2833.

3.  allow=ulaw

4.  On internal calls between extensions, touchtone works fine.

Also, I have reviewed sip.conf with my carriers.

Now for the question:  does anybody know of a carrier that can reliably allow an 
extension in my pbx to send touchtone to a calling party?

I have tried Vitelity and VoicePulse.  Neither can do this, and VoicePulse 
indicates they know it's a problem and will fix it at some unknown time in the 
future.

For the curious, here is the reason for the need.  My wife, who works as a 
translator, will use this extension to receive calls from companies needing 
translation.  When she receives such a call, step 1 for her is to enter an 
employee id code.  At the end of the call, she must enter an additional code to 
receive an ending time.

Vitelity can't do this at all.  VoicePulse works about 75% of the time which is 
not acceptable.

Thanks for any advice.

Chris
