[Asterisk-Users] a few questions

[Stas Khromoy]

we are beginning to test asterisk for our office
one of the features of the current phone system that is very heavily 
used is overhead paging

now i came accross this post
http://forums.digium.com/viewtopic.php?t=2844&highlight=features

that basically says it is not possible with asterisk.

let's hope that i am not understanding it right, since i am new to the 
telephony.

can any one help me out and explain it to the unfortunate ? :))

second question is as follows:

when you access voice mail
the default msg is 'welcome to comedian mail'
is there any way to get rid of this par of the greeting ?


thanks
