We have a Cisco ASA5520 which is using a Comcast cable connection for internet. We have purchased a Cisco UC520 telehpone system. I am looking at purchasing some SIP Trunks and one of the providers is asking that I need to use a PRI card. I am not sure how that would work. Would the ASA take an PRI card ?
The provider that is asking for a pri card is Speekeasy, but there are other providers that may not want a PRI card.
