SIP Trunk Properties
Traditionally telecom trunks are from your local carrier’s PSTN switch and the dial tone
is provided via either analog trunks or T1/PRI digital trunks. A new type of service called
“IP Dial Tone,” which allows you to dial a long distance call at a lower rate, is available.
IP Dial Tone is delivered through your IP data network, and the service provider can be
anywhere in the world, as long as the VoIP data packets can be routed properly.
If you have SIP-based IP dial tone service from an Internet Telephony Service Provider
(ITSP), you need to configure SIP trunk channels to connect the service. Before you
start, note the following:
• An AltiGen SIP Trunking channel is licensed. You need to buy and register a license
to be able to configure this option.
• AltiGen does not guarantee the voice quality of the SIP dial tone coming from your
service provider. You need to work with your data service and SIP trunking service
provider to make sure adequate QoS is provisioned for your WAN service.
• AltiGen does not guarantee SIP trunk implementation will work with all SIP Dial Tone
service providers. You need to verify that your SIP Dial Tone service provider sup-
ports the following:
• G.711, G.723.1, G.729 codec
