SIP Registration

@Skyetel said in SIP Registration:
We have not decided if we want to include SIP Registration in our SLA or leave it as a "Best effort" service. (TBH, I'm leaning toward including it in the SLA)
Absolutely leave it best effort. Registration is a legacy idea IMO.

@Skyetel said in SIP Registration:
We have not decided yet if we want to add registration to all 4 of our regions, or only support it in two.
You chose two just to have some kind of flexible path without having the complexity of making people set up 4 trunks?
Stick with 2 IMO.

@Skyetel said in SIP Registration:
We have not decided on the Registration timeouts - some carriers enforce a full 1800 seconds and won't let you re-register faster than that. We're leaning toward a 6 minute Registration timeout, and providing guidance that you should re-register every 5 mins.
FreePBX and VitalPBX both default to 3600 seconds (1 hour). So going less than that will lead to support calls from "admins" that don't RTFM.

We are worried about fraud risk with SIP Registration.
A valid worry as highlighted by the "admin" that posted here

@Skyetel said in SIP Registration:
What have you guys had experience with, what suggestions or ideas do you have?
Really, the only good thing about registration is when you have an on prem device. Registration will let you get around needing to open firewall ports.

I'm sure we can beta test.

Domain/IP whitelisting?
Enter domain names/IPs that are allowed to register in your account setup.
Domain names are resolved and only IPs that are whitelisted can successfully register.On prem PBX can even have dynamic IP then (with DDNS).
Quite a few services use this layered approach so that it requires both a valid IP and valid credentials.

@Pete-S yeah, there are plenty of things you can add to secure things. But like everything, you can’t fix stupid.

I'm interested in your gentle (cough Jared cough

@Skyetel -- you probably already know this... but...

Well, for customers with this config, we'd just tell them to use our existing IP Registration. We wouldn't need to offer that separately.

@Skyetel I can switch my personal account to registration. Or some spare numbers on our company account. I don't have a "spare" system that will get calls though. So if you can have registration from the same IP as a current endpoint, I can actually do it and have traffic.
Otherwise, it will be sporadic traffic from my personal account, currently hooked up to a VitalPBX instance I am testing.
