Each router has different call handling capacity that it can support. You can refer to this link to confirm the capacity your router model supports.

Based on what you have here, you should be fine.

If you are currently using a single ISDN 30, then that's 30 concurrent calls. Your cisco 2951 can support 500 calls sessions. Cisco 2800 series can do 100 calls

Please note that you need licenses to use the gateway as a CUBE device running SIP sessions

Example:

FL-CUBE-100 will allow you to handle a total of 100 sessions on the 2800 series router

FL-CUBEE-100-RED will allow you to handle a total of 100 sessions on the 2900 series router
