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

[Jim Thomas]

Kristian,

I enjoyed your recent blog praising FreeSWITCH.

The world needs an O'Reilly book about FreeSWITCH.  Perhaps you could write one in your spare time?

Whoever gets there first and does it well is likely to own that shelf space for a long time to come.

Just an idea.

Jim

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.
