SIP provider’s info is entered using the web-based Toolbox Utility, accessible either by the
Comrex Device Manager
software (see
Network Settings
) or pointing a browser to
http://[ip_address]/cfg
. As a reminder, the default login
credentials are
admin

In most arrangements, a SIP provider can deliver several telephone channels to you over a single account. When
you subscribe to a SIP provider, make sure you understand how many simultaneous channels are provided with that
account. These channels will act like a traditional telephone hunt group, so in the case of channel one being busy,
calls will be routed to channel two, etc. You are only required to put in your credentials once for each account even
if you have multiple channels.
Along with account credentials, you’ll need a Direct Inward Dial (DID) number associated with your account.
This is the “old fashioned” phone number users will dial to reach you. VH2 does not need to know this number -
translation to the proper SIP channel happens behind the scenes at the SIP provider (although often the DID and
SIP account name are the same).
In Toolbox, navigate to
Channel Configuration->VoIP Providers->Add Provider-> SIP Provider
. The basic settings
for a SIP provider are shown in the figure above. First, you should give your provider a unique name in the “
Name
”
field. This is used for reference only.
Under the SIP Provider entry, we’ve provided a list of commonly used providers. Using one of these profiles helps
set up some of the more obscure settings that we’ve found necessary for these providers to work correctly. If your
provider isn’t on the list (or if you’re setting up a SIP extension from a PBX) leave this set to “
Generic SIP Provider”
.
The next three fields are where you should enter your account credentials:
Account Username
,
Account Password
,
and
Server/Realm
. These should have been provided to you by the SIP provider.
Account Username
is usually the
name at the start of any SIP URI assigned. (More on that later). E.g.,
username@sip_provider
. Make sure to enter
only the username part.
