[Asterisk-Users] Cisco 7960 bug in 6.1 evident in Asterisk

[Rich Adamson]

No, they don't. I've got multiple 7960's functioning reliably across the
Internet registering (and handling calls) just fine with * for months. And,
the 7960's are behind cheap nat boxes as well. All running v6.0, but worked
just as well with the v4 code. (Other 7960's are on the wire with * too.)

FWIW, asterisk uses a registered IP and the sip definitions include 
nat=yes and canreinvite=no; think I might have tweaked the phone's config
files to register every 600 seconds (don't remember for sure). We don't use
the ethernet switch built into the phone, and each phone has either two or
three buttons defined. The xml directory functions are programmed and
working as well.
