In peer details was "dtmfmode=inband" --> i have change it to auto, "dtmf=auto" was missing so i added it after dtmfmode and now is working.
It's kinda weird because only me has access in to Elastix admin panel, and as far i know i havent edit any config lately.
Thanks alot for your help WelshPaul
I have 3 more question if you can help me:
1. We have IVR, for sales press 1, for service press 2 ... when some1 press 1 or other number it transfer call in to mobile phone number, but the problem is that in that person who awnser calls can only see our fix number, every call which is transfered in that mobile phone shows same phone number 03xxxxxx (our company number) and we need sometimes to get clients phone number. is there any chance to show caller phone number to person who awnsers after transfer is made?
2. How to increase IVR allowed calls number? At this time only 1 person can call our company number, in case user1 is calling, user2 can't call our phone number...
3. We have 10 Grandstream DP750 phones, most of time we can't hear when we call outside or when some1 call us, sound quality is very poor or it stops few seconds... Is there any way to fix this issue?
Thanks again for your help!
