SIP Proxy Server

When connecting to an IP-PBX, it is possible to use a SIP Proxy Server in the IP-PBX instead
of a VoIP gateway/gatekeeper. It is important to ensure the interoperability between the
SIP Proxy Server and the WLAN. See the Ascom extranet > Sales tools > Interoperability.

Connection to Other Systems

Interoperability with traditional telephony systems is enabled via the VoIP Gateway
connected to a main PBX, or directly through third-party H.323 gatekeeper. Interoperability
with messaging applications such as the Ascom DECT and Paging system, or other external
systems (such as GSM) is done via the Unite system. All messaging to and from the VoWiFi
system goes through the Unite module IMS3/Unite CM.
Presence management is supported if a Presence Management system is connected, for
example Netwise.
Two types of location are supported; either AP location which will give an approximate
location of the VoWiFi Handset, or a more accurate location of the VoWiFi Handset by using
a third party location equipment together with Ascom Unite infrastructure components.
See Function Description, Ascom VoWiFi System, TD 92314EN for a description of the
