[Freeswitch-users] Can Freeswitch and OpenSER Co-reside on Same Server?

[Henry Huang]

Kristian:

Can you point me to the wiki link where it describes how to do the header
rewriting and number formatting and topology hiding?
I am also looking into OpenSIPS to be a session boarder controller, but if
freeswitch is already able to do all these, then I think it's easier for me
to stick with it since I already learn and do a lot with it already.

Thanks,
