Hi All, A question for those with Cisco 7940/60 SIP phones. I used to load POS3-06-03-00 Firmware to the cisco phones. A month or so ago, I ran some tests and found that latest 3.8.6 firmware worked well, and solved an issue or two on the phones.
I've a number of users who work outside of the LAN. Our phones use DNS names to talk to A*k, so in theory, just enabling NAT makes the phone work outside the LAN (home users, remote users, etc). However, when we loaded the 3.8.6 firmware to these phones, we've found the phones no longer work outside of the LAN. Using Etherreal, we've found that the communication between the Phone and A*k breaks (A*k never sees the Register packets, but the phone does seem to send them. I'll post more detail if its needed, but I wondered if anyone else has seen this ? The size of the IP packet for register is different (larger on the 3.8.6), but the important content of the Register message seems the same. I've ruled out ISP/firewall interference, as its happened on a number of users. Obviously there are fixes in 3.8.6, so I don't want to downgrade the phones again, but I can't see why they'd fail...
