This only happens between these two extensions, both extensions rights are set the same, we have one main ring group but only extension 1307 is part of the main group and it's a different inbound route.

First of, make sure you're up-to-date on the PBX side.

Also, what phone/softphone do you use for this testing? If a physical phone, maybe someone configured a call forwarding on there. I'd also check the forwarding rules for both users.

Hi,

We are using iPhone app the Kate’s version.

This only happens when direct number is dialed not when you dial between extensions.

No forwarding rules.

Thanks for the assistance
