I have one of the lines of my SPA525G registered to a 3CX extension that I dedicated to a Skype gateway. I created an outbound rule in 3CX where ALL numbers starting with "#" are stripped of the first character and then sent to the Skype route. That way I can use Skype IDs by prepending them with "#". This worked great with a Cisco 7945G. But the SPA525G does not seem to accept alphanumeric characters in its Personal Address Book. So now I have a create a separate outbound rule for every person I call via Skype.
Is there no way for the Personal Address Book to accept a number like "#skypeuserid"?
