Configuring CNAM and 911
~~~~~~~~~~~~~~~~~
This thread started in 2012 so this post is intended to document a more recent
configuration experience.
I started with gv911 (
http://www.gv911.com) for $12 per year. I got that
working but could not live without inbound caller name so I ended up going
with Callcentric for $30 per year. Callcentric bills $2.50 a month but they
will maintain an account balance so I prepay them $30 a year to minimize
accounting.
On Mar 1st, 2019 Callcentric started charging more for their service. Step 1
has been updated to reflect that change.
1. establish a "Dollar Unlimited" CallCentric DID (Direct Inward Dial) phone
number
https://www.callcentric.com/dids/dollar_unlimited_phone_number Note: Dollar Unlimited is a misnomer. DID is technically a dollar but 911 is
also required so the actual cost is $2.50 per month: $1.00 DID + $1.50 911
2. Enable CallCentric CNAM
go to the CallCentric home page for your account
https://my.callcentric.com/home.php click on My Account/Preferences
set "Caller ID with name (Inbound calls)" to Enable
3. go to the OBiTalk Dashboard to register your Callcentric DID number
https://www.obitalk.com/obinet/pg/obhdev find a free SP (service provider) and click through the following pages:
SP<N>/Next/CallCentric
configure the following options:
Configuration Name: CallCentric DID CNAM
Primary Line for Outgoing Calls: uncheck
Voicemail Notification: uncheck
7-Digit Dialing for USA & CAN: <local area code>
Use This Service for Emergency 911 Calls: check
CallCentric Number: <SIP #>
CallCentric Password: <web password>
Note: your <SIP #> is found by going to your Callcentric account home page
https://my.callcentric.com/home.php log in and copy/paste your "Callcentric #" to the Obitalk's
"CallCentric Number" field
4. optional: make SP2 ring pattern "normal" like SP1
enter OBi Expert Configuration mode:
go to
https://www.obitalk.com/obinet/pg/obhdev click on your device under "My OBi Devices"
look to bottom of page and click on "OBi Expert Configuration" then "Enter OBi Expert"
under Product Information expand Voice Services, SP<n> for CallCentric
change Parameter Name X_RingProfile to:
OBiTalk Settings: uncheck
Value: A
5. assuming the Callcentric status is "Registered" on the
OBi Dashboard Status, add and verify the CallCentric phone number to
Google Voice:
go to
https://voice.google.com/voicemail Find the three vertical ... and click to expand more options
go to Legacy Google Voice/Settings/Phones
click on the Settings wheel in the right hand corner
click on "Add another phone" and go through the process
uncheck forwarding to Google chat
check CallCentric
6. test 911 by calling 933
