Audio issues and NAT


We have been using the cloud hosted solution for a number of weeks without many issues (the odd teething issues to start). As of last week we have started experiencing issues with people not being able to hear callers, but the callers can hear the user. We are using a Technicolor router in the office.

The firmware version is showing as:
PBX Firmware:

As we are using the cloud solution, i am unsure what NAT policies we can put in place internally to address this (if any) Has ayone else experienced the same issues with the cloud solution?

We have also experienced issues whereby an inbound call will come in fine, this will then be transfrerred to another extension. The next inbound call then appears to disconnect the previously transferred call if still active.

Any recommendations would be greatly appreciated.


Is NAT enabled on the Extensions?
