Hi all<br>
<br>
I am getting the feeling you are going to be hearing alot more from me
in the near future.<br>
<br>
I have yet another issue here. This time its with DTMF (again).<br>
<br>
Ok the setup is as follows:<br>
<br>
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.<br>
<br>
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.<br>
<br>
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.<br>
<br>
Can anyone tell me what I can do to enable the DTMF to work?<br>
<br>
Thanks in advance.<br>
<br>
Ian<br>
