Hi,
I am not too familiar with the topic and I tried researching on the Net, but could not find anything that makes it clear to me. So, I would be grateful if anyone could help with the following.
My requirement is to setup a CISCO device with SIP device(s) that will appear to the switchboard as a single SIP trunk and be able to keep adding PRI cards so it never ran out of lines without having to reconfigure the switchboard.
To test proof the concept I want to use the 30 channel PRI card. But which Cisco PRI card will support SIP trunking?
Also, which router should I use with a SIP device that will allow me to continue adding more and more channels/cards.
The SIP trunk should support an infinite number of calls if it has the available bandwidth.
Thanks in advance
Andrei
