Extension DID
When selected Extension DID, select an extension in
the list to be an unconditional destination for incoming
calls to this trunk. If prefix or stripping has been given,
the result of digit manipulation is dialed in a DTMF
string after the call has been answered by the DID
extension as an automatic 2
nd
dialing.
If you set a DID extension in a trunk, then only that
extension can use this trunk to call out, and all
incoming calls to this trunk will connect to that
extension directly.
DID By Number
When selected DID By number, enter configurations in
DID Prefix and DID Stripping to have the incoming calls
directed to the corresponding extension derived by
number manipulation. The trunk numbers is therefore
regarded as the direct line of the extension.
DID By Privilege
When selected DID By Privilege, select a usergroup in
the list as the privilege of inbound calls from this trunk.
Enter configuration in DID Prefix and DID Stripping to
have the incoming calls redirected to dial out.
