IAX2 Trunking, IVR Issue

[klept24]

Hi Support,

This is my scenario
2 Elastix server connected thru IAX2 Trunk.
Calling from Server A to Server B okay, vice versa.
Calling IVR of Server A to extensions on Server A, okay.
Calling IVR of Server A to extensions on Server B, cant go through.
Error "invalid extension"


TIA!
