[cisco-voip] Inserting a pause in an outbound dial with a PRI

[Craig Staffin]

I ran into the same issue working with sites in China (Shanghai)

If it is ISDN you have no chance to do anything as far as delays.

However I do know that I had a lot of problems making sure that the ISDN
plan type was set correctly.  This took me a week with a very fluent
Mandarin/English translater.

If I remember correctly the city local 5-8 digit needs to be local and all
else needs to be international.
