Title says all.  Decided to switch to Comcrap Triple play, which bundles Video, Internet, and Telephone.

I do not very comfortable to use their modem/gateway/router (Xfinity) due to every time their tech guys show up for service call, they all have tendency to replace the current modem/gateway/router you have.

Since I have a camera system with DDNS configured on the router.  If these tech guys decide to replace the router, I'll be on square one to spend sometimes to reconfigure the DDNS again.  It seems like PIA.

I've been looking for an alternate third party Modem, Router, and/or WAP whichever does have telephone connection since I have the Triple service.

I'm open for suggestions...  TIA
