I came across this forum from a link in Github..

However, I need a twist to it because of the following reasons;

1. I am using Fanvil IP Phones that require to be pointed to .xml file.
2. Client wants both multiple numbers on the phonebook directory - Extension and Cell Phone.

Here is the twist;

1. Script to be generate .xml file in /tftpboot Directory
2. xml file should contain extension and cell number
3. script should update xml file periodically when cronjob runs the bash script.

Can someone help me out with updated script. I dont mind paying for it.

PS: Documentation below shows favil is compatible with yealink syntax
