CUCM version 6. MGCP GW router. Dial Plan is 4 digit dialing. In CUCM, the External Phone Number Mask is set to full E.164.
When the GW fails over to SRST mode, I know that the ephone is automagically created with the 4 digit DN.
Question 1 - Is there also a secondary number created reflecting the full E.164 so enable to phone to ring for both 4 digit and full E.164 number calls?
Question 2 - If the answer to Question 1 is yes, what number is forwarded out of the gateway on redirects (for example, redirecting a UCX) - the 4 digit primary or the E.164 secondary?
