7960 connection drops after initial successful test

tblair2323 · ‎03-04-2007

I have the 7960 set up on a VPN which other applications use. There seems to be no conflict with other system applications.

After the initial configuration, calls can be received and made successfully for about 3-5 minutes and then nothing connects.

Outbound calls have fast "busy" signal after about 30 seconds of nothing.

In-bound calls will not successfully pick up the incoming line.

Calls to other extensions and the voice mail system end with a fast "busy" signal.

I am using a DSL filter on the incoming IP line and have tried removing with no luck.

Thank you for your help.

Hi,

is this CCM or CCME ?

can your browser open telephone's web page from the remote end of VPN ?

Yes, we can open the browser from the remote end of the VPN

I am on the server end. Tim is my user. We are using CCM 3.3. I have never seen this type of problem before. This was a phone purchased from eBay by the user. Other than that, it's the same as we always use. We wiped the config and set it up the way all of our other phones are setup but no go.

Any help is very much appreciated.

SOLVED:

Problem was with deep packet inspection on the remote VPN router. Increased DPI settings to max and it now works.
