I really hate CUPS.

Really.

Cisco CUCM 5 and 6 bug

The latest bug to hit my inbox is that apparently when CUCM 5 and 6 hits 248 days of uptime, it can crash horribly. Cisco's advice is to reboot the CUCM servers before they hit the 248 day uptime counter. Resetting them effectively resets the counter.

Very very worrying.

Cisco Presence

It's been a while since we tackled Presence due to the instability of older clients and the CUPS server behind it. However now we're starting to see that the client especially, has come a long way.

I've always believed that CUPC is the pinnacle of how Unified Communications (from a Cisco point of view at least) should work, and just so happens to be the tool of choice to sell other Cisco products into a customer's network because of it's ability to tie everything together.

Below is a brilliant video of how it works.

caller-id enable

Hi all,

Just an interesting case that came up very recently where a customer had 'caller-id enable' on all of their FXS ports on a VG224. The result was that calls to analog phones on the VG224 would not answer correctly if you picked up the phone during the first two phones. This is because the gateway is incorrectly configured to send caller-id signal in the analog stream. Turn it off to alleviate the symptom.
