the difference is the VIC2-4FXS/DID can provide DID feature on the single port , which means the single port with DID feature can route the incoming call from the PSTN to the destination number ( ip phone extension) , so u don't have to buy an E1 line for example to have the DID feature on it , you can just make it works on your analog VIC2-4FXS/DID . <br>this is all the information i got regarding what you were asking for .<br><br><b><i>Jonathan Charles <jonvoip@gmail.com></i></b> wrote:<blockquote class="replbq" style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;"> So, I have 2801s and 2811s at remote sites, and I have a VIC2-4FXS/DID<br>card in the router, but that card only shows up on the 2801....<br><br>There is an option for a VIC-4FXS, is it the same thing?<br><br><br><br><br>Jonathan<br>_______________________________________________<br>cisco-voip mailing
