I’m using asterisk 126.96.36.199
when dialing out with the TE120, I’m having unreliable DTMF experiences, some IVRS work, some do not. in the sence that DTMF recognition is not optimal. For instance, when pressing a digit a tad too long, will result in the IVR seeing 2 digits.
I have gone through most of the variables:
toneduration=500, 1000 (is it good to try 2000?)
also I have set only alaw and ulaw on all extension which are gxp2000’s but also softphones have this problem, which leads me to assume it’s not on the extension side.
I would create a support ticket for this, as this is a very urgent problem, but I am in now way able to retrieve the Serial Number (remote location on customer’s side. No Access whatsoever).
I would be very appreciative of anyone that can help me… maybe even a moderator/staff member can still open up a support ticket for this.
edit: I forgot to mention I also tried all dtmfmode settings in the sip.conf file and it does not make any difference.
