No it has much value to me.

I was already suspicious about Zoiper as I could send fax between other
endpoints.

Originally, I thought using the same software on both could help to validate
other settings (tuning of sip.conf) but to my surprise I couldn't find much
about Zoiper fax capabilities.
I have the rough feeling Zoiper can't receive fax at the moment or either,
tuning Asterisk to allow that is not simple.
For sending, I won't rate it at the moment.
