Hello,
Zoiper for Linux does not support CLI or protocol association. The protocol association is available with the Windows version of Zoiper 3 Biz, which supports callto, tel and zoiper protocols with the following syntax:
callto://
callto:
zoiper://
zoiper:
tel://
tel:
Zoiper 3 also support the following command line parameters:
Show Zoiper windows if hidden or minimized:
show
Hang an active call(Biz only):
hang
Call a number:
call=[ phone number ]
dial=[ phone number ]
dial_string=[ phone number ]
Search for a contact(Biz only):
find=[ filter ]
Send fax to number(Biz Only):
fax= [ number ]
fax_file=[ number ]
These 2 load an account configuration file.
add_account_file=[ path to file ]
add_account_url=[ url ]
Some of them might actually work on some Linux distributions.
