I've just upgraded a Rls 3.0 Opt61 to Rls 6. The ITG card was replaced with a sig_server/MC32s card. I programmed the IP trunks as IPTI. Now, I get a err648 (No TN for ITG card) on both inbound and outbound calls on this route. Anyone know what causes this? I've got all the patches in the CPIV card and sig server. The MC32s firmware is what came with card. I didn't have any patches for it.
