Session Initiation Protocol (SIP)
IP Office supports SIP trunking. SIP trunks allow IP Office users to take advantage of new telephony services
being offered by ‘Internet Telephony Service Providers (ITSPs)’. In many cases, these telephony services can
offer substantial savings in comparison to traditional exchange lines. The IP Office solution allows all users,
regardless of their phone type, to make and receive SIP calls. SIP trunks are handled like any other line on IP
Office, affording all the call routing and toll control needed to manage inbound and outbound calls.

SIP trunks on IP Office require the provisioning of voice compression channels through the installation of VCM
modules within the control unit. A license for the maximum required number of simultaneous SIP calls is also
needed. Up to 128 simultaneous calls are supported.

reference architecture for IP Office.
