Using Linphone with Comrex STAC VIP
Introduction
Linphone is a free SIP calling app available for
iPhone, Android, and other platforms.
Comrex STAC VIP is a multi-line talk show system
that can
1) Take pure Internet (SIP) calls from the
outside world
2) Process calls that use wideband
(HD Voice) codecs like Opus
Linphone supports the Opus codec, and is a great
way to connect to the STAC VIP from smartphones.
Opus is supported in STAC VIP 1.1p4 firmware and
higher.
Setting up the STAC VIP
In order to take calls from Linphone, you must register
STAC VIP with an Internet telephony provider that
will support taking SIP calls from the Internet. Our
favorite choice is onsip.com, as they will accept
calls from user’s whose phones are “unregistered”.
In this way, you don’t need to enter any special
SIP registration data into your phone. Many other
providers will require that Linphone be registered to
the same provider as STAC VIP (and most will provide
a free SIP account for that purpose). Linphone
registration is left to the reader—our example will
use onsip with Linphone in “unregistered” mode.
An email will be sent to you to activate your account.
Once activated, a confirmation email will be sent.
This will include a link to login to your account.

First, you will create a new account at Onsip.com.

Make sure the following entries are set correctly:
1) Name->LinphoneIncoming (or any name
you like)
2) Outgoing Enabled (your choice, Linphone will be primarily incoming)
3) Color Code->(your choice, chooses banner
color on caller interface page)
4) SIP Provider->OnSIP
5) Account Username -> Username (from
credentials)
6) Account Password-> SIP Password (from credentials, long string of characters)
7) SIP Proxy Address-> Outbound Proxy (from credentials)
If any error messages appear here, carefully check
the credentials as they were input. Also, be sure
UDP Port 5060 is not blocked for outgoing data.
Now you must assign this provider to one or more
unused lines, so calls can be received. This is done
by backing out to the main configuration menu and
selecting Line Configuration->Line Assignments.
As shown in the example, the first three lines have
been assigned to the “Main Provider” the next two
have been assigned to a “SIP Trunk”, and the last
seven have been assigned to onsip (to take calls
from Linphone). You may use as many lines as you
like for Linphone, onsip will forward multiple calls to
your STAC VIP on a single account.
8) SIP Domain-> Domain (from credentials)
9) Auth Username-> Auth Username (from credentials)
10) Proxy/Domain-> (Domain from credentials)
If all these parameters are correct, Choose “Restart
System”. Once the system returns (about 10
seconds), check SIP Registration status as shown:
