How do I register my PBX to Nextiva’s SIP trunking server?

There are a few prerequisites before you register your local PBX to Nextiva’s SIP Trunking servers.

1.) It is required that you create a device within your Nextiva SIP Trunking Portal. Creating a device will generate a unique set of authentication details necessary for the PBX to register with Nextiva.

Step 1

  

2.) When creating the device within the portal, you will be asked to fill out information regarding the address where this device is located. This is critical as it is generating the E911 information associated with your local PBX.

Step 2

3.) In this step you will be asked to choose from one of two options.

  • Manually Enter
  • Randomly Generate. (Recommended)

This applies to the authentication details necessary for your local PBX to register or authenticate with Nextiva’s SIP trunking servers.

Step 3

4.) Now that the authentication details have been generated, you may register your local PBX to Nextiva’s SIP trunking servers by using the following information.

EXAMPLE OF A REGISTRATION STRING
AUTHORIZATIONNAME:AUTHORIZATIONKEY@trunking.voipdnsservers.com/AUTHORIZATIONNAME
(If we were to use the information used in the screenshot it would appear like this)
Register String : 828849783:610712364@trunking.voipdnsservers.com/828849783
HOST : trunking.voipdnsservers.com (This is Nextiva’s Host/Proxy Server)

5.) As each local PBX’s web interface and infrastructure will vary, there may be other details necessary to ensuring that the PBX is fully functional. The registration information above details the core-requirements necessary to register your PBX.
NOTE: Other PEER DETAILS may be necessary to ensure that the PBX is registered and functional :
Disallow=all
Allow=ulaw
Username=AUTHORIZATIONNAME (replace with the values generated from Trunking Portal)
Fromuser=AUTHORIZATIONNAME (replace with the values generated from Trunking Portal)
Type=friend
Secret=AUTHORIZATIONKEY (replace with the values generated from Trunking Portal)
Qualify=no
Maxexpirey=3600

Insecure=invite
Dtmfmode=auto
Session-timers=refuse
Defaultexpirey=60
Nat=no
Canreinvite=no
Context=from-trunk

6.) Create an Outbound Route for the Trunk to be accessed from
ROUTE NAME: A descriptive name for the route
OUTBOUND CID : AUTHORIZATION NAME (replace with the values generated from Trunking Portal)
DIAL PATTERNS : Typically, select all dial patterns except “information.” (Directory services are not supported through Nextiva SIP Trunking)
TRUNK SEQUENCE : Choose the name of the Trunk you created

7.) Create Extensions for the user’s phones
Choose Generic SIP Device when asked to select model of phone (if applicable.)
DISPLAY NAME : The name of the user assigned to the device
OUTBOUND CID : AUTHORIZATIONNAME (replace with the values generated from Trunking Portal)
DEVICE OPTIONS
SECRET : desired password for the exte4nsion
DTMFMODE : auto
CANREINVITE : no
CONTEXT : from-internal
HOST : dynamic
TYPE : friend
NAT : yes
PORT : 5062
QUALIFY : yes
DIAL :sip/TYPEXTENSIONHERE
MAILBOX : TYPEEXTENSIONHERE@device

8.) Create an Inbound Route for the DID of the Trunk
Select from your “Inbound Routes” section of your PBX and input the following information:
DID NUMBER : AUTHORZATION NAME (replace with the values generated from Trunking Portal)
DETECT FAXES : Set to NO

Note: With this information you should be able to register and provision your local PBX.

While Nextiva supports many different types of SIP Trunking devices we offer limited support regarding the physical application of entering the following information into the PBX. If you are experiencing challenges registering your PBX please contact the manufacturer of your PBX and provide the criteria listed above.
