Randomly Handsets not ringing

Asterisk Asterisk Support
1

PJSip extensions randomly stop accepting calls. We use a mixture of Yealink and Grandstream handsets. Extensions appear registered at the tim eon both the handset and asterisk

When logged to Yealinlk they responded with this when ext 9992 calling 237.
The server send the Invite signal to the 237 that the 9992 want to talk with 237, and 237 send 100 Trying and 180 Ringing to the server that it has received the Invite, but then server send Cancel signal to 237 cancel this call. So that is why the call cannot establish.
Thanks Mark

You need to show a SIP trace.

Also this looks like a FreePBX dialplan, and this is not the right forum for FreePBX dialplan related issues.

I hope this is as requested. Thanks Ext 258 ringing 243 and 243 reporting handset not ringing
