When we have failure at Phase 1 means that we can have basic communication issue. Check conectivity and if IP address are correct configured on both sides.

[Richard Burts]

Checking for IP connectivity is an excellent place to start. Another frequent cause of Phase 1 problems is that the pre shared keys do not match. And of course it is always a good idea to chack to make sure that the parameters used for ISAKMP on one side do match with the parameters used on the other side.
