I'm setting up various Cisco IP phones in a non-Call Manager 
environment, but I'm having some problems with the config files. The 
Cisco documentation is rather sparse on some issues.

1) After reading the .cfg.xml config files from the TFTP server, the 
7902G and 7912G phones ask for the profile files "United_States/ff<MAC 
address of phone>" and "United_States/gk<MAC address of phone" respectively.

Apart from the fact that the Cisco docs states that the "ff" prefix 
should be "ld" for the 7902G (and makes no mention of a locale 
subdirectory), there doesn't seem to be a plain text sample profile file 
anywhere on warp.cisco.com (yes, I know the file needs to be converted 
to binary with cfgfmt). Anyone got a working sample?

2) In a Cisco Call Manager environment, you can change the locale for 
the phones, so that menus are displayed in whichever language the user 
wants. How/where is this configured?

3) Is there a way to reset a 7902G or 7912G over the network? (I seem to 
recall that the ATA186 units could be reset using a special URL.)

4) I've set up a 7902G, a 7912G and a 7960 with SCCP ("Skinny") against 
an Asterisk server. I'm using chan_sccp, not chan_skinny. The 7902G and 
the 7960 are working just fine, but sometimes when I call the 7912G from 
an external SIP client, the call connects but when answered, no sound 
can be heard at either end of the call. Also, the phone tends to report 
that it's "busy" when clearly it is not. Has anybody got this phone to 
work reliably with Asterisk, using SCCP? How about SIP?

Any help would be much appreciated.
