Make sure that both ends match:
Start with output of "show cry is sa" - look for QM_IDLE
MM_NO_STATE is problems with ISAKMP phase I
   check pre-shared keys
   check peer IP address
   check transform sets match, ie. 3des/md5/group 2
   check timeouts match
   enable/disable keepalive both sides

"show cry ip sa" look for error packets, one-way communications (decrypts but no encrypts, or encrypts but no decrypts)  
Access-lists to define the VPN traffic (local lan) - (remote lans) are mirror images both sides

double-checked all ipsec & isakmp paramaters...

show cry ip sa - I'm not seeing any traffic...

my network is 192.168.1.xxx however the IP range I have to use is 192.168.10.xxx - something else on the pix need to be changed?
