Despite many hours of searching manuals and this forum, I have been unable to figure out how to use a calling card for outgoing calls. I have a Linksys SPA3000 configured as a trunk. It is operating well for both incomming and outgoing calls. I would like to use a calling card for outgoing long distance calls. I can see how to add prefixes using the outgoing dial plan on the trunk, but can't figure out how to wait after dialing the local access number. Any clues would be appreciated. Thanks.
