We have a Yeastar S300 with 1 SIP Trunk.
When we setup "Call forwarding" to external numbers or even the Mobility Extension features, all calls fail with "Invalid Phone Number".
Any ideas why? Or is this due to setup from the SIP Trunk Provider

Thanks I actually followed that article at first. Anyway we solved part of the problem by changing the Diversion settings for the SIP Trunk.
