About Smartnodes

Patton Smartnodes are used by many in the sipXecs community. While not supported directly by sipX, they offer a feature rich solution as an unmanaged gateway. The primary configuration interface for smartnodes is CLI and the routing core is built upon a very flexible modular structure. Unfortunately, the learning curve for configuring these devices can be quite steep.

This document will provide a basic understanding of the configuration for a typical sipX installation. The following sections will guide you through each step. Rather than cut-and-paste your first configuration, you may find it more beneficial to configure your first device by following the steps below to gain an understanding of how all the pieces connect to make a functional and flexible gateway solution.

Setup Networking

Setup your DNS SERVER

dns-client server DNS.IPA.DDR.ESS

Setup NTP services (Be kind to the net and use pool servers

sntp-client server primary port 123 version 4
sntp-client server secondary 1.north-america.pool.ntp.orgport 123 version 4
sntp-client poll-interval 36000
sntp-client local-clock-offset

Create NAPT profiles (If using the smartnode as a router/firewall)

profile napt NAPT_WAN
profile napt NAPT

Set the Hostname

system hostname SIP-GW.YOURDOMAIN.COM

Set Default Gateway

context ip router

Setup WAN and LAN profiles (Some models only have one ethernet port)

context ip router
interface WAN
ipaddress dhcp
use profile napt NAPT_WAN
tcp adjust-mss rx mtu
tcp adjust-mss tx mtu

context ip router

interface LAN
ipaddress LAN.IPA.DDR.ESS
tcp adjust-mss rx mtu
tcp adjust-mss tx mtu

Bind the interfaces to your profiles

port ethernet 0 0
medium auto
encapsulation ip
bind interface WAN router
no shutdown

port ethernet 0 1

medium auto
encapsulation ip
bind interface LAN router
no shutdown

Setup ISDN (T1/E1/BRI)

Setup US Tone Profile

profile tone-set US
map call-progress-tone dial-tone US_Dialtone
map call-progress-tone ringback-tone US_Alertingtone
map call-progress-tone busy-tone US_Busytone
map call-progress-tone release-tone US_Busytone
map call-progress-tone congestion-tone US_Busytone

Build a routing table

context cs switch
routing-table called-e164 PSTN_TO_SIP
route .%T dest-interface IF_SIPX

Create the ISDN interface profile

context cs switch
interface isdn IF_PRI_1
route call dest-table PSTN_TO_SIP
use profile tone-set US
caller-name send-information-following

Bind the inferface to the T1 Port

port e1t1 0 0
port-type t1
clock slave
linecode b8zs
framing esf
encapsulation q921

uni-side user
encapsulation q931

protocol ni2
uni-side user
bchan-number-order ascending-cyclic
encapsulation cc-isdn
bind interface IF_PRI_1 switch

Setup FXO

Enter FXO setup here

Setup FXS

Enter FXS setup here

Setup SIP (5.x Method)

Build a routing table

context cs switch
service hunt-group OUTBOUND
drop-cause normal-unspecified
drop-cause no-circuit-channel-available
drop-cause network-out-of-order
drop-cause temporary-failure
drop-cause switching-equipment-congestion
drop-cause access-info-discarded
drop-cause circuit-channel-not-available
drop-cause resources-unavailable
route call 1 dest-interface IF_PRI_1

context cs switch

routing-table called-e164 SIP_TO_PSTN
route default dest-service OUTBOUND

Build a location service

context cs switch
location-service SIPX_SERVER

Build a sip gateway and bind it to your LAN

context sip-gateway GW-SIP
interface IF_SIPX
bind interface LAN context router port 5060

context sip-gateway GW-SIP

bind location-service SIPX_SERVER
no shutdown

Create the sip interface and bind the gateway

context cs switch
interface sip IF_SIPX
bind context sip-gateway GW-SIP
route call dest-table SIP_TO_PSTN

Example Configurations


Patton 4114 (4 FXO) - TESTED - Config verified for simple setup with sipXecs.

Patton 4524 - TESTED - Config verified for simple setup with sipXecs.


Below are configurations for different types of Patton Smartnodes. Some confiurtions are 4.x and others are 5.x. The 5.x code release presented changes the the SIP configuration which prevents 4.x SIP configs from working with 5.x. Follow the "Setup SIP" Section above to make the necessay changes required for a working 5.x configuration.

Patton 4114 (4 FXO) - 4.x Config

Patton 4118 (4 FXO, 4 FXS) - 4.x Config

Patton 4960 (4 E1 T1) - 4.x Config

Patton 4960 Firmware version 5.2 - 5.2 Routing inbound DID's to sipX

Patton 4524 (4 FXO, 4 FXS) - 4.x Day / night & weekend call routing in the Patton

Patton 4524 (4 FXO, 4 FXS) - 5.x To login to 4 extensions on the PBX

Patton 4524 (4 FXO, 4 FXS) with SIP Trunk to - 5.x SIP trunk to Concentric acting as B2BUA.
