I need to register my WP820 with 3CX v16. I see that there are some templates and config like: WP820_config_18.104.22.168.txt and WP820_config_v2_22.214.171.124.xml which I saw in the forum but when I try to load the template to my 3CX I have to change the extension file from xml to .ph.xml but doesn’t work.
Is there other method or a manual?
Could anybody help me?
Thanks in advance.
