I purchased a PANASONIC KX-TG2740S 2 line cordless phone just like 

http://catalog2.panasonic.com/webapp/wcs/stores/servlet/ModelDetail?storeId=11251&catalogId=11005&itemId=62849&catGroupId=11104&displayTab=F&surfModel=KX-TG2740S&surfCategory=2.4GHz%20MultiTalk%201%20x%208%20Expandable%20Systems&ignoreRedirect=1

I am using the phone in England UK. I have two questions

1) How can I get the caller ID to work here in UK. I assume UK and US
have different caller id systems.

2) I use a cheap carrier to make international calls and I would like
to program that as part of the phone number in the momory but it does
not take so many digits. How can I get around this? ie I would like to
save very long numbers (25 Digits) in the memory.
