1140E dropping call

[mattb025]

Issue : Group of 1140e's at remote site dropping calls. Phone is not cycling or logging out. Calls at main site no issue.

System info

1140E, CS1000E with ver 7.5, AACC.

I have seen this when the phone looses connection, but phone shows no sign of network lose, just call drop.

Are these internal calls or external calls?

If a trunk is involved, is something happening to the DSP channels that terminate the trunk?

Any additional detail you can provide will help people here make an intelligent diagnosis.

Do you have a PC plugged into the Phone ? If so it could be using wrong port.

Sounds like networking issues between the site where the PBX is and the remote site where the 1140's are.
