2 Calls being created when calling a number

This is a bit of an odd issue and it isn’t happening all the time.

When someone makes a call from an extension, can be either internal or external, sometimes 2 calls to the same number are initiated.

We are using Yealink T23G Handsets.

Has anyone else noticed behaviour like this before?

Current Asterisk Version: 13.16.0


Nope. Sounds like a flaky phone/firmware, need a call trace to see what’s going on.
