Feature : Call Forwarding
When *72 and 91XXX XXX XXXX is entered , the PBX comes back with a message :
" Unable to complete the call as dialed "
Every time I attempt to activate Call forwarding via using *72 - I get an unable to complete your call message from the PBX . I spent a day researching this feature and within Grandstream as well and have found that this feature never worked ? We searched for any sort of trunk transfer or forwarding parameters that we could change but could not find any . We also searched on and Tried changing the dial plan rules also to no avail . This Friday 3-27-2020 I will be working with my Customer to obtain a network trace to see what is going on . I am taken back by the fact that this major feature does not work and there is no valid solution except work around’s . Does anyone know the technical reason for this not being able to call out on a second trunk / Line ? Has Grandstream responded in re to a fix work around or a bug ?
