Hi alexnuno nice to hear from you, though sorry to hear this is still occuring.
Off-hours are 11 pm to 5am in pbx's timezone. The next best bet would be to work with support so that we could look at logs on our side. I've gone ahead and created a case for you and someone from our support team will be reaching out.
Hi Kate!
Thanks so much for this! I worked with support yesterday and think we found the solution. Apparently it's surprising that our phones were working at all given how they were deployed. There were a couple of core GTC Firewall rules that needed to be set, as per the deployment requirements. Either these were never set in the first place, I inadvertently affected rules at some point, or a recent firewall update messed with our settings. Apparently this is a semi-common issue that at least the tech I was assigned has seen around, so I am praying that this is indeed the fix.
- SIP ALG needed to be disabled.
- UDP Keep Alive needed to be set to 300 seconds.
- Ports 5060-5061 needed to be allowed through the firewall.
The changes have been in place for 24 hours, with no mass provision yet.
Fingers crossed.
Thanks again for all of your help Kate! Best to you!
