If you search the archives there have been other questions like this but more
from a "I don't want people to know we use FreeSWITCH or Open Source" point
Have a read of the valid replies why FS branding at some levels stays
in and your options. I'd
be proud to show off FS and just want to hide version/git numbers.
Even if you did hide that you can still work out it's FreeSWITCH, but
sofia is an open source Nokia stack so it doesn't mean FreeSWITCH straight
FreeSWITCH is respected and an extremely reliable product (plus all the other
praise I'm too tired to write!) and should be honoured. It's saved us a fortune
with our VoIP interconnects and we try to put money back into it (got
a project starting
soon re billing/LCR etc.).
