Hi Guys, Just a quick question, we are new users to 3CX not VOIP in it self but to 3CX managing the calls etc. We have a dedicated 2mb adsl/sdsl hybrid line ( not sure of the full actuall type of the line but i know its a bit of a mix ) and we have a 16 users licencse for concurrent calls. Basically we are getting very muffled audio on calls at times, our suppliers of the system are trying to work through the issues but its taking some time I was wondering if anyone would have any ideas ? I cant see any pattery as to when the bad audio happens, we very rarely go above 5 concurrent calls in any one time, i have noticed poor quality when they are this amount of calls but also when we have only 1 call so im not entireley convinced its to do with bandwidth etc. Any help would be greatly appreciated.
