I have a customer with 2 Aspires 7.32 with a couple of IP Phones that were working fine until the made some changes to the fire wall .The phones come up and are kind of half working the say "network busy" you can not make or recieve calls but they do show the extension number and when you call the extension it ring and you can see the caller id but when you answer the call you get a busy signal and the call drops

Any Thoughts

Well it depends on what changes were made to the firewall. These are pretty temper mental. Make sure they did not remove any port forwarding for the IP sets. Are you doing NAT or VPN? Also check each phone for speed and duplex. Set all phones to 100M instead of AUTO. This helps with these phones!

I suspect the firewall is blocking ports for RTP and RTCP. The phone is connecting to the network, and the signalling is working fine - the voice traffic is carried by the RTP/RTCP protocol, usually defaulted to run on port 5060-5061.

I found where to change the the speed & duplex

I can barley read the display (another issue)

but it did not make a difference .

from what I understand the data company did not make any changes to the fire wall on the side where the ip phones are pointing to, but he did change the other side .

Are the phones working on VPN or NAT?

If you can call the phone, and it rings, then the phone is registered to the server, and the signalling protocol is working.

I still suggest your problem is most likely in a firewall at one end of the circuit or the other, that is not allowing the RTP/RTCP protocols to pass.......
