@clydfan SIP traffic is not blocked.
When I work from home , I have a SIP phone connected into the company PBX.
However you do need to check that your Broadband Firewall setting is either LOW or OFF

If you are trying to host a FreePBX system behind your home router i.e behind NAT , then you will almost certainly need to request a static IP (£5 one-off charge) as you will need to configure FreePBX with your public IP.
Also, if you are using the PN supplied Hub one , I'd suggest getting a more configurable router, particularly one which allows any SIP Alg to be disabled as they are often broken and don't work correctly.
Superusers are not staff, but they do have a direct line of communication into the business in order to raise issues, concerns and feedback from the community.
