can you telnet to the remote side on TCP 179?
telnet x.x.x.x 179
debug ip bgp x.x.x.x <- neighbor address
also debug ip packet to look for TCP 179 packets - this will show you your BGP packets going out, and hopefully reply packets from the ISP (or vice versa) - NOTE, dont turn on "debug ip packet" without an ACL if the interface is busy!

if you didn't see anything at all when you did sh ip bg sum then you didn't enable BGP on your side.
do sh ip protocols and see if you have BGP there, see if you set neighbor relation with the ISP...

show ip bgp summary
you will see that the peer should be Active or any other they a number
Neighbor V AS MsgRcvd MsgSent TblVer InQ OutQ Up/Down State/PfxRcd
10.100.1.1 4 200 26 22 199 0 0 00:14:23 23
10.200.1.1 4 300 21 51 199 0 0 Never Active
in this example you see that the peer to 10.100.1.1 is OK as you can see you recived 23 updates but the status to
10.200.1.1
is Active and the up/down is showing you nevered formed a peearing with that peer.
