I have been asked to trouble shoot an issue where a certain SIP ACK packet is not making it through the firewall across an IPSEC VPN from a 3cx PBX to a 3cx soft-phone. This making calls drop when they go on hold.
With Cisco devices I could probably get to the bottom of it but this set up is using a Unifi router which I am somehow administrating from a centralised cloud controller. Even if I could SSH into a command line I wouldn't know whether to SSH into the box or into the cloud controller. I don't have the luxury of access lists or any decent logs.
Any Unifi guys out there with any tips? I am prepared to learn a little bit of the CLI as my boss (an MSP) has deployed these things everywhere.
