[asterisk-users] DTMF Issues

[Adrian Marsh]

What version of Asterisk are you running? What setup ?

I've just hit issues with 1.4.19.1 (see previous post)...  Same
symptoms-ish.

Hi all

I am getting the feeling you are going to be hearing alot more from me
in the near future.

I have yet another issue here. This time its with DTMF (again).

Ok the setup is as follows:

We have a few Grandstream BT 200 phones and a few X-Lite phones. When
dialing out to, say a bank, with the Grandstream the bank complains that
it is unable to detect our DTMF tones. However when I do the same with
the X-Lite it detects it correctly.

Now I am in the process of implementing authentication into the system.
This on the other hand detects Grandstream DTMF but not X-Lite DTMF.

The Grandstream phones have been set up to send their DTMF via sip info
(I set it up that way in order to use the *2 transfer feature). I have
tried Zoiper and when I set it up to also send DTMF via sip info, the
asterisk detects the DTMF correctly.

Can anyone tell me what I can do to enable the DTMF to work?

Thanks in advance.

Ian
