Good Morning Folks,

I am working with our Network Admin to get VOIP running. He has installed the VOIP in the Cisco router and dropped my a CAT 5 cable. I am connecting this to a TN464F which is configured as a standard DS1 as well as Tie trunk.

When the Trunk first comes up, I get dial tone and things seems to work just fine. After 5 minutes or so of idle time, the connection drops and goes to an "Out of Service" state.

Here is the trunk config Page 1:

I know without knowing the setup on the router it's shooting in the dark, but has anyone here run into anything like this.

I appreciate any assistance you may offer.
 
I think I figured it out... I switched to Robbed Bit, and it seems to be holding the connection now.
