10.4 SIP Proxies and SIP Gateways
The Allworx servers support connectivity to external SIP-compliant devices such as Internet Telephony
Service Provider (ITSP) servers and SIP gateways. The Allworx products interface with four different types of
SIP devices based on how they interact with the Allworx system:
SIP Proxy
– A SIP Proxy refers to a SIP Trunk, an external SIP service for routing calls. The SIP Proxy is
accessed through the Internet or through the wide area network (WAN). To connect to a SIP proxy (or ITSP),
it must be configured on the Allworx server. Application notes for configuring Allworx servers with approved
ITSPs are available on www.allworx.com
SIP Gateway
– A SIP Gateway is a SIP-compatible device that extends the connectivity of the Allworx PBX.
Examples are FXO, FXS or T1 expander gateways. Typically, SIP Gateways connect to the Allworx server
via an Ethernet interface directly to the Allworx server LAN.
SIP Handsets
– A SIP handset is a SIP-compatible phone that registers with the Allworx server. See Section
8, Adding Handsets for information about connecting Allworx or 3
rd
-party SIP handsets.
Remote Allworx
– A Remote Allworx is an Allworx server at another site that is configured to behave as if it is
part of the local system. The remote system need not be the same server model as the local Allworx system
but it must be running the same software version and must be using the same number of digits for its
extensions.
