Nortel Contivity to Cisco 1710 VPN

[Guest_imported]

I have been working with a Cisco TAC engineer and searching newsboards and the internet for help, to no avail. I am trying to setup a VPN from a Cisco 1710 to a customers Nortel Contivity Model number - Ces1500D Software number - Vos_6105. The tunnel appears to come up but no traffic will pass. I have since taken my 1710 and conected it to another Cisco router, via a VPN and had no problems what so ever. As per a segestion from another newsgroup I made sure that the lifetime on the IPSEC and ISAKMP are the same on both sides. I get no decrypts or encrypts when the ping in intiated form either side but the tunnel does come up.
