Thanks. The primary focus isn't for dialing from site to site. It is
trying to keep from having to come through our server at corporate when
a remote facility is calling or receiving a call to/from the PSTN. We
don't want to have remote sipx systems if we can help it. These are
small remote facilities.
Is it impossible to support what Verizon describes with centralized Sipx
setup?

You would connect remote sipx systems and connect them to verizon as
you have your central system. You would then create a dialplan to
allow them to route calls directly between each other (sipx to sipx).

Excuse my ignorance here if I'm butchering some terminology. After a
pretty successful roll out at our corporate office, we are looking
possible implementations at some of our remote facilities that
have old
dying key systems. All our facilities are connected to our corporate
office by Verizon T1 MPLS links. From a network perspective, they do
have the ability to hit the Verizon cloud directly without coming back
to our corporate office first. Verizon is our VOIP provider. Our
desire
is to send the RTP traffic from a remote facility directly to Verizon
without coming to corporate first. We do not want to put any equipment
at the facility, except the handsets. We want to utilize our central
Sipx server(s) at our corporate office. Verizon says they can let the
sip traffic go through through corporate, but then route the RTP
traffic
directly out the local port. This is the description from Verizon
on how
this works:
"The term we use for allowing the RTP media to flow directly from our
VoIP node (SBC) directly to your remote office is called “Media
Release”. The opposite of that is “Media Anchor” (aka hair pining)
which
requires the media to “anchor” to the IP PBX and uses 2x the bandwidth
into and back out to the remote."
Is this something Sipx supports? I tried Googling Sipx and "media
release" but I don't get any hits. Maybe there is a different term I
should be using. We have Cisco routers at each location if that is
relevant.
Sipx 4.0.4, sixbridge, Verizon VOIP, No firewall (not needed, private
connection), Polycom 450s and 550s - bootrom 4.2.1, firmware
3.1.3C split.
Thanks as always,
Matthew
