I am looking for what you would recommend for a setup for a small branch office using the 2801 series. What we would need is something like this for the initial setup, the big thing is that we want VOIP. This is huge. However I don't know much about the ins and outs of this, I do believe that you can connect to POTS so you have a 1 to 1 translation.
We currently are running a Pix 515 FW on the facility, however I gather you can replace the FW with the router due to the intergrated security features. We also have a 2600 router that is not in use, can we add a voice module to that which will connect via POTS, or add a voice module to the router and install a CallManager server? Any guidance for us would be great, we are a small brance office running a cablemodem at the moment however I hope to be able to move to FIOS in the near future. Thanks guys, appreciate it!
