4.2.1 What network facilities do I need to provide?
This may vary widely depending on how your network is constructed and what else it is
carrying, but as a general guide you will probably need:
• A SIP proxy server (to route calls)
• A SIP registrar server (frequently combined with the proxy server) to resolve URIs to
IP addresses
• A TFTP server (for downloading configuration files).
• A TCP Syslog server (for reporting alarms and external inputs)
• An SMTP server (for reporting via email)
• An STNP server (to synchronise the internal clock)
Dedicated systems, such as Gatekeepers, VoIP-enabled PABXs or soft PABXs may also
provide these functions. Bear in mind that GAI-Tronics telephones only support Session
Initiation Protocol (SIP) to RFC3261, as opposed to H.323 or SCCP VoIP protocols for
example.
Note that the performance of VoIP telephones depends on the provision of sufficient
bandwidth and prioritisation on the network to give the quality of service required.
4.2.2 How do I set up dialling and memory lists?
Let's assume you have a telephone with 2 buttons: memory 1 for information, memory 2 for
emergency. You want the emergency button to call "888" only. You want the information
button to call the information desk, or if that is busy the security office, or failing that the
administration centre on 223344.
First set up the 4 possible user agents (end points) as memories on the memories page (it
doesn't matter which end point is in which memory):
Note that comfort strings have been set to give the user confidence that "dialling" is taking
place when the button is pressed.
Then set up 2 memory lists, one for each button:
