Add option Multicast paging

[tbagwell]

Could you add somewhere to the paging as to setup a Multicast paging. Right now have to set it up in the extensions_custom.conf File

We happen to add this.

exten => 77,1,Dial(MulticastRTP/basic/224.0.0.1:1234)

if you could add it. It will be nice. Or even set it up to where you can add more then one multicast also. Like.
exten => 77,1,Dial(MulticastRTP/basic/224.0.0.1:1234)
exten => 78,1,Dial(MulticastRTP/basic/224.0.0.2:1235)

Thanks.
