Losing calls right around 30 seconds every time.
Two sites. Both with UniFi Security Gateways. Primary, original building, has a Ring-u hub which is a repackaged Asterisk system I believe. Phones are Grandstream. Everything in the primary building works fine with that system.
New building is connected via a Site to Site VPN that I set up using the UniFi interface with VPN Type AutoIPsec VTI. Currently have one phone at the new building. It works fine except that calls always drop around the 30 second mark. They can be intercom calls to the primary building or calls to outside numbers.
The phone is a Grandstream GXP1630. We’ve tried using TCP for SIP Transport. Also tried TLC/TCP. Default was UDP. Ring-u suggested to try TCP first as they thought UDP was timing out in the firewall.
On the USG firewall settings, under Settings - Routing & Firewall - Firewall - Settings under CONNTRACK MODULES I have SIP off and H.323 on. This is how it was set, have not changed anything there.
I tried setting STATE TIMOUTS, UDP Other from 30 seconds to 28,800 but that didn’t seem to matter.
The Ring-u folks have been helpful, but I’d like to see if anyone here has any insights before I go back to them.
Thanks in advance!
