[asterisk-users] Polycom Remotely Cancel Call Forward

[Kai-Uwe Jensen]

When setting a forward on the phone, the phone will upload to your ftp
server a modified macaddr-phone.cfg XML file that (amongst other
locally made changes) contains an OVERRIDE statement similar to this:

<OVERRIDE reg.1.fwdContact="xxxx" reg.1.fwdStatus="1" ... />

Change the .fwdStatus attribute to "0", then reboot the phone (sip
notify polycom-check-cfg peername). That will removed the forward just
fine, at least in my setup here.

Works the other way as well: modify the XML file to list a valid
.fwdContact  and set .fwdStatus to "1", then reboot the phone. That
phone won't ring again until the forward is disabled :)
