If the message is coming from the Summit then it is not an IP problem it is a routing or trunk config problem, at least I think it is. However it could also be software version problem with the MBX. I have seen where it will not talk to an SBX or Summit without an upgrade. If that were the case I would upgrade it to a Summit 800. First thing though is to recheck the did/isdn trunking setup for both sites.
