I am working on allowing a third party VOIP solution to have the phones (Lan side) connect out to a cloud based provider (WAN - Telus).

Their provided documentation asks for the ports in the attached photo to be opened.

Can someone provide a nudge or example for how you would go about doing this?

I have been creating a traffic rule like the following...

Source: Firewall AND Trusted/Local Interfaces
Destination: Any
Service: Self created group that contains individual services created to try and replicate what is in the provided table.
IP Version: Any
Action: Allow

The trouble for me is the Protocol column in the table. I seem to only be able to allow services via the usual TCP/UDP, or either of those. Then a random smattering of "Protocol Inspectors" from there. Nowhere though do I see an allowance for SIP/TLS/SRTP. How would I add those entries?

Once I have opened up enough access for the techs that are doing the onsite install tomorrow, I will work on skinnying this access down to just the phones. DHCP reservation the phones and add them to an IP Group which will only get the rule.

Any conversation around this would be helpful. I am spinning my wheels a bit.

Well, for what it is worth. I took my best stab at creating the traffic rule and services for this. The outcome was successful, so don't worry about giving this too much further thought.
