== Things to investigate ==

⚫

* ~~Check the quality of~~ the internet connection

When did the problem start? - what changed around that time?

* Was phone system upgraded?

* Was the telephone software upgrades?

⚫

* Was the internet connection changed?

* Was the internet router changed?

* etc

Then:

* Check the quality of the internet connection - broken audio can be down to a poor internet connection

* Calling *100 will play a continuous 1Khz tone - if the audio breaks up then there is a problem

* Check the CQM graph (if using A&A for the internet connection)
