<font size="+1">I'll reply to the list since it seems of general
interest. My company makes C4 Softswitches but I'll stick with
general recommendations.<br>
<br>
Common commercial manufacturers include ourselves, GenBand, Sonus,
Oracle, Switchray (aka Mera), Kamalio, Cataleya and others. Most
of these will cover your short list of requirement.<br>
<br>
However you may also look for other relatively important features
since your Softswitch investment will last a long time and your
network requirements can change. Common other features to look at
or plan for include:<br>
<br>
1. Access/Subscriber side SBC functions for hosted C4/PBXs like
Broadsoft.<br>
2. DOS/DDOS detection and mitigation.<br>
3. Fault tolerance or HA operation (ie, stateful switchovers).<br>
4. LCR and/or billing applications to control off net routing.
(another whole world of features exist on this subject)<br>
5. TLS/SRTP support. <br>
6. Good monitoring applications for performance alerts and
troubleshooting.<br>
7. Transcoding support.<br>
8. VM deployment options.<br>
<br>
The debate about the value of open source is ongoing and subject
to change. Alex addressed this subject well but it is worth
noting that some large carriers are embracing open source
solutions so that they can modify the functionality themselves.
Alternatively many small carrier select open source so they can
save money on capex costs although this will normally lead to
higher opex costs for management.<br>
<br>
On the subject of OS I would recommend staying with Linux and
avoid a Microsoft solution. The real time nature of media
handling seems to be problematic for Windows although potentially
the Intel DPDK technology may mitigate some of these problems.<br>
<br>

<div class="PlainText">Hi All,<br>
<br>
We are in the process of going down the path of deploying
our own Softswitch infrastructure to transition away from
purchasing from SIP Trunk providers and moving to getting
CTS direct from VoIP Carriers.<br>
<br>
There seems to be a lot of solutions out on the market and
weeding out the "Built on Asterisk" / "Built on Freeswitch"
with little or no support vs Commercial Supported solutions
is proving to be difficult.<br>
<br>
There are the "leaders" (or strong marketing companies) such
as Broadsoft & Metaswitch - but what I am trying to
uncover is what else is great out there that may not have
the exposure but is worth looking at.<br>
<br>
What we are looking for...<br>
<br>
1. Class 4 Softswitch<br>
2. Geographical Redundancy (Active - Active)<br>
3. Preferably not built on Freeswitch or Asterisk (Not
saying they're bad just tired of OpenSource for Core
products)<br>
4. Must have commercial support available (preferably during
Australian hours)<br>
5. Windows or Linux doesn't phase us - we have skill set on
both platforms.<br>
<br>
Happy to hear the good, the bad, the ugly, the war stories
so that we can get some real world feedback on what's out
there, what works, what doesn't and hopefully not make the
same mistakes that others have already made.<br>
<br>
Offlist replies are perfectly fine if you don't wish to
discuss on-list.<br>
<br>
Thanks in advance and enjoy the rest of your weekend! :)<br>
<br>
Cheers,<br>
<br>
Greg<br>
