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.

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.

Not shure if it helps here, but we had nearly the same dtmf problem in an asterisk 1.4 install with SNOM 320/360 phones. After hours of fiddling arround, we used relaxdtmf=yes in sip.conf and the problem went away. Guido _____ Von: Ian [mailto:asterisk at iancoetzee.za.net] Gesendet: Mittwoch, 30.
