Provisioning Guide M700, M300 Introduction

PNP

Plug & Play (PnP) provides a proprietary method to enable provisioning on M300 and M700 DECT base

stations. By default the base stations send SIP SUBSCRIBES messages to a multicast address. Any

SIP server that understands the message may reply with a SIP NOTIFY message containing the URL

of the provisioning server from where the phones can request their conﬁguration. An example SIP

SUBSCRIBE message from the base station would look like this:

SUBSCRIBE sip:MAC%3a0004136*****@224.0.1.75 SIP/2.0

Via: SIP/2.0/UDP 10.0.0.90:5060;branch=z9hG4bKl1d23iyadenuaa1jr4vm

Max-Forwards: 70

From: <sip:512@10.0.0.90>;tag=dmrud.mzfyg66

To: <sip:MAC%3a0004136*****@224.0.1.75>

Call-ID: 6cm70qdo.o.8i@10.0.0.90

CSeq: 20264 SUBSCRIBE

Contact: <sip:512@10.0.0.90>

Accept: application/url

Allow: INVITE, CANCEL, BYE, ACK, REGISTER, OPTIONS, REFER, SUBSCRIBE, NOTIFY, MESSAGE, INFO, PRACK,

User-Agent: snomM700/03.23.0005 (MAC=0004136*****; SER= 00000; HW=255)

If any SIP application within one-hop range understands this message, a SIP 200 OK conﬁrmation is

sent, followed by a SIP NOTIFY message containing the provisioning URL. The base station accepts

this message and conﬁrms it with a SIP 200 OK.

snom Redirection Service

The snom redirection service allows customers to register/list/unregister the MAC addresses of

their M300 and M700 DECT base stations on snom's provisioning server and assign a redirection

URL pointing to their own provisioning server. The service is designed to implement an easy-to-use

interface (XMLRPC) for interaction with remote client applications. The communication between

server and remote client application is secure. A detailed explanation can be found here:
