[cisco-voip] Best practices for a 7936?

[Robert Kulagowski]

I've got a site where 7936's seem to have one-way audio issues; after a 
call is made, the other side can hear outbound audio, but we can't hear 
them.

The 7936's are running 3.3(11), which is the latest firmware.

Looking at the forums on Cisco, some solutions were 1)  Hardcode the IP 
address on the phone, since there appear to be issues when the DHCP 
server reboots  2)  Hardcode the speed and duplex on the phone and the 
switchport to 100/FDX.

Of course it only fails when there's a critical call that needs to 
happen, and our solution is to reboot the phone, but that's not viable 
long term.  And once we get to this point, where the phone is only 
working one-way, calling TAC so they can troubleshoot why it's happening 
is a non-starter, because the conference call _has_ to happen.

Anyone else experiencing these issues with 7936's?
