VH2 Quickstart Guide
The VH2 is a studio telephone interface device designed to work on VoIP telephone systems. This guide will
give you the minimum you need to know to get the system hooked up and running. For more details on how
to configure more complex arrangements, see the full user manual.
Specifications
The VH2 can handle one or two VoIP accounts (a single account can be assigned to both channels).
The unit has the ability to easily transfer the call on either channel back and forth to a companion VoIP phone.
Caller output audio is available of balanced XLR-M. Send input is available on balanced XLR-F. Clip levels on
XLR feeds are +20dBu.
On-hold audio input is available on a ¼” TRS jack. Two channels may be fed to “on-hold” callers via “Tip-
sleeve” (channel 1) and “Ring-sleeve” (channel 2). These inputs are unbalanced and the clip level is +20dBu.
VH2 has a single 10/1000 Ethernet jack for network connection. The companion phone should be located on
the same physical LAN as the VH2 (no routers between them).
The approved companion phone (Polycom VVX201) can be powered from PoE networks. The VH2 cannot.
The companion phone contains a 2 port Ethernet switch, so the units can be wired as follows:
PoE Ethernet Jack ->Polycom phone->VH2.
If a PoE is not available, you must use the provided power adapter with the Polycom phone.
Requirements
To configure and start using the VH2, you’ll need the following information:
1 The user name, password, and server address of a cloud-based VoIP service, an available
account on your PBX, or similar information in order to utilize VH2 on a gateway device.
2 An available static IP on your network, including gateway, netmask and DNS server information.
3 Knowledge of how the VH2 will be attached to your studio audio ports. The choices are:
a VH2 can take a single “send” feed from your console, or two separate “send” feeds.
b VH2 can deliver a single “caller” feed to your console, or two separate “caller” feeds.
c VH2 can be fed a single “on hold” input, two separate “on hold” inputs, or none at all.
d VH2 can be configured to allow callers to hear each other when “on-air”, or they can be
isolated from each other.
e “Send” and “caller” feeds can be connected via analog or AES3 signals.
