The customer states that prior to putting a MT router in he never had the issue with his Cisco.

If you're on the same L2 segment, but completely different IP subnet, it still caches your IP/MAC pair. There's no way, at least that I know, to clear it, you have to reboot the radio. Telnet in and run 'arp -a' and you'll see what I mean.
