The voice connection is disconnected.

[freedomtoy21]

I am currently using the Cisco 3660 router.
I am using 4-port Voice PM for MARS port adapter to connect the FXS Voice daughter card (2 port) and FXO Voice daughter card (2 port) to the other area. When I use it well, the hot line becomes dry. Then, when you reboot the cisco 3660, the cisco 3660 returns to normal. And for a while, I get used to it again. Then reboot the device and it will work again. I repeat this. Is there a way to find the cause?

Can you elaborate more, I'm confused with the terms you are using.
"When I use it well, the hot line becomes dry."

or

"And for a while, I get used to it again."

What port are you using FXO or FXS? What type of phone/device is plugged there? can you share your dial-peer configuration?

Please can you share the "show running-configuration" of your router and be a bit more specific of the problem that you face, as Ronaldo describes?

Thanks in advance,

George
