SIP Trunking Configuration Guide

2| Cisco SPA8000 8-Port Telephony Gateway SIP Trunking Configuration Guide
INTRODUCTION
These Notes describe the procedures for configuring Session Initiation Protocol
(SIP) Trunking between service provider Intermedia.net Inc. (Intermedia) and a
Cisco SPA8000 8 Port Analog Gateway. The Interop was performed with an
Iwatsu ADIX-VS Phone System (Analog PBX) as the analog end point to the
gateway. The Iwatsu ADIX-VS phone system is an analog PBX connecting with
RJ11 to the SPA8000. This Interop is not limited to this analog phone device.
The Intermedia SIP Trunking service referenced within these Notes is designed
for business customers. The service enables local and long distance PSTN
calling via standards-based SIP trunks directly as an alternative to legacy
analog or digital trunks, without the need for additional TDM enterprise
gateways and the associated maintenance costs.

INTERMEDIA SIP TRUNKS
Intermedia Configuration Information
You should have the configuration information from Intermedia before you start
the install. This information will provide settings for the SIP connection(s).
The information you will receive from Intermedia will be composed of the
following information. Your order will be different from this information:
Primary codec: G.729
Secondary codec: G.711
SIP TRUNK ID dgwsid10941
PASSWORD ********
DNS NAME usbc.accessline.com
IP ADDRESS 64.28.113.10
PORT 6060
Call processing has been setup to allow up to 2 simultaneous calls.
The following 911 callback number has been configured in our
network as the default for this location; please test and make sure you
are able to present this as the 911 callback number and program it to
route appropriately on inbound.
2065172775
This can also be used for testing inbound calls and has been setup as
the default for outbound CLI. The following additional test number has
also been provisioned.

FIREWALL/ROUTER SETUP
Make sure that Ports are forwarded from your router to your internal IP address
of your IP office system.
SIP-based VOIP enabled PBX or SIP phones connected to Intermedia’s Service
via our SIP trunking service MUST be installed in a secure trusted zone behind
a Firewall and not exposed to the public internet. This means the PBX or SIP
phones should never be put into a router's DMZ (allows untrusted access).
The firewall must block all inbound internet (untrusted) traffic to the PBX or SIP
phones. The firewall can be configured to allow inbound traffic from trusted
devices from remote (satellite) locations.
You do not have to block outbound traffic from your private network to the
internet, but Network- Address-Translation, or “NAT” must be enabled. NAT
allows the Intermedia Service to send calls to the PBX or SIP Phones. If the
firewall has multiple NAT settings, you must select the NAT setting that
“Address Restricted” and not “Endpoint Independent”. If you do want to limit
outbound internet traffic on the firewall, then you need to open SIP related ports
on the firewall to allow Intermedia’s Service to function properly.
Protocol
Port(s)
UDP
6060+
UDP
30000 –50000
NOTE: The ports are the default ports that are configured by Linksys 5060,
5061, 5160, 5161, 5260, 5261, 5360, 5361. These defaults ports will work with
Intermedia’s service, unless there is some NAT router that detects 5060 as sip.
In this case then remap to 6060 range.
Basic Configuration Instruction:
Configuration of this device is performed through a web GUI built into system.
You will also use a telephone and SPA-8000's built in IVR to determine the
devices IP address.
1. Connect the equipment to the network and apply power.
2. Determine IP address.
a. Connect phone to port 1.
b. Dial **** to activate the system menu.
c. When the menu system responds, dial 110#. The system will read off
the IP address of the SPA-8000.
3. Connect the laptop to the same network the SPA-8000 is connected to.
4. Open web browser and navigate to the IP address of the SPA-8000.
5. Click on "Admin Login" on the top right hand of the page. This should
change to "User Login".

6. Click on "Advanced" on the top right hand of the page. "Advanced should
turn back and "Basic" should turn blue.
7. Now to configure the SPA-8000 SIP trunk, Select the "Voice" tab on the top
of the screen and select the "T1" tab.
PBX CONFIGURATION AND SETUP
Two separate Intermedia SIP trunks were configured, one for voice with G729,
G711 and one for fax with G711 only. The SPA8000 was configured with 2
voice lines L1, L2 that work with the voice trunk T1. The fax trunk T2 is using
line L4.
SIP TRUNK CONFIGURATION - VOICE
Configure the Voice Trunk T1 with the Intermedia SIP Trunk credentials. Enter
the information as detailed below using your supplied Proxy Address and
username and password from Intermedia. The voice trunk will hunt across lines
1 and 2 in this example, enter hunt rules in the “Contact List” section.

SIP TRUNK CONFIGURATION - FAX
Configure the Fax Trunk T2 with the second set of provided Intermedia SIP
Trunk credentials. Enter the information as detailed above using your supplied
Proxy Address and username and password from Intermedia. The FAX trunk
will use line 4 in this example, enter hunt rules in the “Contact List” section.
