Implementation of a feature that will disable "missed calls" counters on SIP phones.

Browse Source 
If the call is answered by another phone, other phones won't display the call as "missed".
You can also add an option to the dial command so that you can have a "followme"
scenario and not count the calls as "missed" when you cancel the call.

Thanks to Ramon and Frank for feedback on this feature.
