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

So do you build your server with two FS instances running?  One as the SBC
and one as Proxy/PBX?

Thanks,
Jerry

You can use different IP addresses or ports.  I do this all of the time.

I question why you are using OpenSER (OpenSIPS?) as a SBC.  FreeSWITCH is
actually more well suited to most of the functions served by something
called* a "session border controller".

For example, FreeSWITCH in bypass media mode is a signaling only SBC where
you can (cleanly) do the header rewriting, number formatting, and SIP
topology hiding typically done by a SBC without touching the media.  Proxy
media mode can do the same while proxying media (traversing NAT and hiding
real RTP addresses).  FreeSWITCH in normal bridging mode can transcode,
convert between different types of DTMF and do everything else mentioned
above.

OpenSER as a proxy can't even (per RFC3261) rewrite To or From, nor will it
hide topology (it simple adds Record-Route/Via).

* Session borders controllers are very ill-defined and mean different things
to different people.
