Digium Updates Switchvox 4.5

Modern PBX phone systems often have lots of capabilities
that end-users never actually see, since they don’t actually directly use
the PBX — they use the phones that the PBX enables. That’s a situation that
VoIP vendor Digium is aiming to change with the new release of Switchvox

Switchvox is Digium’s commercially licensed VoIP IP PBX and was last updated a year ago for
enhanced unified communications collaboration services. Digium itself is
best known as the lead commercial sponsor behind the open source Asterisk IP
PBX effort, which also serves as the base for Switchvox.

“Switchvox 4.5 is all about the users and how they interact with the
system,” Tristan Barnum, director of Switchvox product marketing for Digium,
told InternetNews.com. “We’ve always tried to give them different
ways to access their data and voice tools like voicemail. What we’re doing
in 4.5 is something we call phone feature packs, which extends the
functionality of Switchvox out to the phone itself.”

Barnum said that users can now find and activate new applications through
their phones that previously they could only access via the Switchvox Web

For example, Barnum explained that when Polycom IP phone users hit the
phone’s “services” button and they are connected to a Switchvox PBX, they’ll
get a list of applications that they can now access. Among the applications
are fully searchable directories as well as visual voicemail and call

“It just represents a really tight integration between the handset and
the Switchvox system,” Barnum said.

Initially, the phone feature packs are set to work with Polycom IP
phones, though the effort will be expanded other phone vendors over time:
Barnum noted that the system is built to be ported and uses standard XML
system calls.

“We had to do a few special things, and that’s why right now it just
works for the Polycom phones,” Barnum said. “There is nothing that isn’t
reusable that we won’t be able to push out and do for other types of

Among those other phones is a soon-to-be-released Apple iPhone
application as well as one in the works for BlackBerry users as well.

Secondary server support

Switchvox 4.5 also adds another major feature: A new level of
scalability, with the ability for a phone to subscribe to more than one
Switchvox PBX.

“We can now expose a secondary server,” Barnum said. “Previously, phones
could only subscribe to one server, but now if your primary server goes
down, the phone will look for your extension on a completely different

The secondary server provides the opportunity for Digium and its partners
to sell additional Switchvox servers, giving users a backup phone system
that can be off-site.

Opportunity from Avaya’s Nortel buy?

With the new Switchvox 4.5 PBX release, Digium is also aiming to take
some share from customers who might be thinking about shopping around in the
wake of Avaya’s integration of Nortel.

“Any consolidation in the industry drives people to look around for
alternatives,” Barnum said. “As well, people are getting more educated and
open to the idea of open source. We see more resellers looking into Asterisk
and when they hear about Switchvox, which makes Asterisk accessible to them.
It’s a good situation for us.”
