Remote IP Phones with Cisco 871w

[h382]

I have a remote office I put a Cisco 871w in along with 3 IP Phones connected back to the main site. The phones and everything are working, 2 way audio, etc.

The problem I am having is that some calls disconnect. Could be after a minute, could be after 3 minutes. Also, the screen on the 5610 sometimes flickers. Like the button labels go away, or the whole screen my flash.

Anyone have any idea what I can check?

Just happened to me.

Couple things. It doesn't drop the call, you just can't hear. The timer keeps going. And also when the phone is idle, and the screen flickers you see the button names under the specified labels. For instance I have a Support button that is just a dial feature to our Support hotline. I see that support #, and then the word Support comes back on the screen.

Also, the MWI goes out for about 1 second.. then comes back on.. Only happens intermittently.

Are the phones connected back to the IPO with a VPN?

Yes, sorry I should have mentioned that.

Also, since we have multiple offices on our MPLA network, and the 871w gave me VPN access into out network, I tried registering the phones with another IP Office, and they worked, but with the same issues as mentioned before.

At the same time, I do have a couple remote IP Phones across the MPLS connecting back to the main site with no issues. So the issues only seem to arise when VPN is involved.

There is a timer involved
Could it be the old fashion H323 fixups ?
