I have an IPO 500 that has been working fine for nearly a year. We're using SIP and suddenly we started getting one-way transmissions (we can't hear incoming callers) and cannot make an outbound call.
We didn't loser power, make any network changes (router, firewall, etc) or make any configurations to the IPO. We contacted the carrier and they don't see any traffic leaving our network and confirmed the SIP trunks and server on are up and okay.
We're on R6.0 with a VCM32/ATM4 card. We reset all hardware (modem, router, switch, IPO, firewall) and no improvement.
Could the card or other hardware have gone bad? Any other ideas?
