Question : VPN between Sonicwall TZ2460 and Cisco 881

I am trying to get VPN set up between a Sonicwall TZ2460 and a Cisco 881, the settings seem to be the same on both ends but the tunnel wont come up.  The Sonicwall says that IKE Phase 1 is not working.  Does anyone have a config that works for the two or help me point to a setup tutorial.

This is a Site to Site VPN

Thanks

Typcically, when I have challenges, it's the local and peer IKE IDs that are giving me fits.  The link below is what I use quite a bit.

I've set a lot of these up and have been quite successful at it, so I know it's possible.
