Hello,
I have Cisco 2851 router with 2 FXS port card which is inherited from another sister company. I would like to use this router in LAB using on analog line and installing CUCME version 8.1.
My question is Can I directly connect the rj11 to FXS port and start calling ? I dont have any PBX.
Thanks

You do not need to install anything to make calls on this router as CME is built into IOS, you need to enable it with ‘telephony-service’. You can then connect analog phones to these FXS ports.

Hi, FXS port is intended for connect analog phone instead FXO which intended for connect PSTN analog line.
But You need PVDM for work with analog telephony

No, as pointed out you need FXO ports for that, which for 2800 router you can get for few $ on eBay along with PVDM2-8 that you will need.
