I am "testing" a Cisco 7937g phone but it appears that the firmware is 220.127.116.11 but that is not whats in the plugin load /var/lib/plugins/xivo-cisco-sccp-legacy/templates/7937.tpl. It has P0030801SR02 as the firmware file. This Firmware is for the 7940 and 7960 phones.

I had to flash the 7937 from a test tftp setup. Got the firmware version upgraded. The phone is very unstable until i placed 19 custom fuction keys into the user field.
I read in an early forum Asterisk-France 5years ago that part of the problem with working with 7937 config was that there was no 7937 phone available.
I would like to offer a 7937 phone shipped to where it is needed if it can help repair Wazo 7937 implementation.
