If you are using a dial prefix I am sure you are frustrated that you can’t simply use the call list to redial.
The Polycom UC software v3.3 and greater provides the following variable:
dialplan.applyToDirectoryDial="1"
Setting to one applies the digitmap to the directory when dialing.
In our case inbound calls had the e.164 strings so it was easy to craft a search and replace digitap:
dialplan.digitmap="R+1R9Rxxxxxxxxxx|0T|[2-8]xxx|**xxxx|9011xxx.T|9[2-9]xxxxxxxxx|91[2-9]xxxxxxxxx"
I hope this helps someone.
