Over the last few days, we are getting 15 second delays for all calls. If I dial an internal extension, it takes 15 seconds before the other phone begins ringing. We have the same problem for inbound and outbound calls, too.
Where do I start looking to fix this?
I see alot of these errors in the console:
[2019-07-08 17:50:45] ERROR[C-00000024]: pbx_functions.c:610 ast_func_read: Function PJSIP_HEADER not registered
Other than that, the only thing I can think of is that it’s a DNS error, like in this thread, but I’m not sure how to go about solving that or figuring it out.
