Good morning all!

We are having issues with setting up our soft-phones. We currently have Trixbox 2.6.2.5 with a very simple setup. We have Aastra i57 hard-phones and are have no issues at all with them. We are moving to have a few soft-phones installed but are having issues once the call is made the touch tones are not being recognized.

We are using Zoiper and are interesting in purchasing it once the demo proves to be a success. We have trouble shot and tried the basic items that we could find by searching forums. We have forced the DTMF to rfc2833 we have tried inline but still nothing. The Zoiper soft-phone will register and make/receive calls but once the call is active no tones are recognized. This proves to be a major issue as IVR or transferring is not working.

Please let me know if there are any things that I can try...
Thank you in advanced!!!

This is probably not an issue with zoiper or any other softphone. You will have to check your other settings too. I personaly like zoiper and use it for all my sip calls and ivr testing without a single issue of dtmf or anything else. As a first point of troubleshooting check your jitterbuffer settings. Check for something like this

;Enable Jitter Settings
jitterbuffers=4
jbenable=yes
jbforce=no
jbimpl=fixed
;jbimpl=adaptive
jbmaxsize=500
jbresyncthreshold=100
jblog=yes
;tos=0x18

and disable accordingly. Hopefully it should work then.
