SkySwitch implementations, traversing firewalls (alien.top)

I've been an ITSP for almost two decades and the single biggest PITA with respect to rolling out new account over these years has been traversing the firewall. If you're an MSP and have control over the premise firewall, it can still be tricky with some edge equipment. But if you have no control over what that equipment is and no admin level access to it, then it is often a negotiation with the MSP or IT department to modify the firewall.

We are starting to migrate our customer accounts from a variety of platforms over to SkySwitch and am interested to hear from other Skyswitch ITSPs on how they make this as easy as possible. We have some legacy accounts on a Broadworks switch that have Edgemarc on prem but that's not a viable or economical solution going forward. We have some on 3CX and their SBC approach has been great, especially with special firmware for Yealink T5x series that can make any one of them an SBC for up to 10 phones each. The phones register through them and the tunnel it sets up is firewall-proof.

What's solution to get around the firewall issue?

Talking about skyswitch, can anyone point me to a freepbx/pjsip config example? I fudged one together the other day and want to compare.

Skyswitch. Gross. That MSA is a disaster.

TLS + a good SBC, you’ll never think about firewalls again.

I haven’t touched a customers firewall in over two years. Albeit, I am writing my own platform lol.

Preferred SBC?
