For customers that have restrictive networks, there may be some ports that are required to be opened to our service which are included below.
Destination: Variable / Not Fixed
SIP: 5060 and 5061 - TCP and UDP
RTP: 10000 and 20000 - TCP and UDP
As the end point IP is not fixed based on cluster and fail over, this should not be limited to a single destination network otherwise you may encounter a loss of service expectedly.
For protected networks, please ensure that any SIP ALGs you have are disabled unless they are known to work reliably as they can cause issues with call routing, stale registrations and inability to make and receive some calls.
