Introduction; Pre-Requisites; Constraints - Vertical Xcelerator IP Manual

Introduction

Configuring Vertical's Xcelerator IP PBX for use with Cbeyond's BeyondVoice with
SIPconnect service offers you and your customers significant cost and voice quality
benefits over using one of the legacy interfaces with a gateway. This document
illustrates the requisite steps to get the Xcelerator IP to register with the BeyondVoice
with SIPconnect service. It narrowly focuses on this scope and should be used in
conjunction with the general Xcelerator IP configuration and installation documentation.
SIPconnect is an industry standards-based approach to direct IP peering between SIP-
enabled IP PBXs and VoIP service provider networks. If you would like more
information about the SIPconnect Interface Specification, which was defined by the SIP
Forum in their Service Provider to IP PBX Interoperability Task Group, go to

Pre-Requisites

• Before using this document, it is required that the implementer be qualified in
configuring Xcelerator IP.
• The Xcelerator IP Firmware must be v1.5.4.0 or higher.

Constraints

The interoperability testing performed did not include any STUN or fax testing. It is
recommended that you use the analog ports on the IAD, that Cbeyond supplies with the
service (two of the analog ports are complementary), for faxing. Also, it is strongly
recommended that if a firewall is used on the customer premise, it should be SIP-aware
(ALG compliant).
