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 Mobility Connect in CallManager 6.0

Hoorah! Today I configured CallManager 6.0 Mobile Connect and it's a fantastic feature. When someone calls my DDI both my IP Phone and my Mobile Phone ring out, and I can choose to answer either. If I hang up on the mobile, I can pick up the call on my IP Phone without the call dropping, and should I choose to, I can transfer the call from my IP Phone to my Mobile seamlessly.

Ace!

2 problems to take note of:

- The first problem is what you set on your mobile phone as your voicemail. My problem was that originally my mobile phone was forwarding to my IP Phone extension in the event of forwarding to voicemail. If someone calls the mobile it would go to my extension (and ring out if I was logged in, otherwise would go to my Unity VM).

Now what will happen, is that if someone calls my mobile, it will forward to my extension which is logged off, which will in turn call back my mobile in a sort of strange loop. A possible fix for this is to get Unity to recognise your mobile number as a number that can access your mailbox directly, and get the mobile to forward to a generic VM pilot number instead of your direct extension. I will update when I have a solution to this.

- Problem 2 is the obvious issue of timers between making calls and having enough time to answer them. Be careful with timers as it takes a while (A LONG time if you use a GSM gateway :D) to build the call to the mobile. By the time your mobile starts ringing the CM will already have reverted to VM!

The best guide (Which isnt very good) to setting this up is the Cisco SRND for CM6.0
