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 to 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.
AltiGen dealers are notified of AltiGen-tested and certified SIP-Trunk service providers. Configuration
guidelines for each AltiGen-certified SIP-Trunk service provider can be found in the AltiGen authorized
Partner Knowledge Base, available from the AltiGen Partner Web Site. SIP dial tone service providers
need to support the following:
•
G.711, G.723.1, G.729 codec
•
RFC 2833 for DTMF tone delivery
•
SIP MD5 authentication with SIP registration
•
If MAXCS is behind NAT, verify that your SIP SP can support this configuration.
When subscribing to a SIP dial tone service, typically your service provider will provide you with the information
required in the configuration dialog box shown in (see Figure
144). Enter these service parameters
to each SIP trunk channel configuration individually.
Note:
This is signal only trunks. Make sure you have enough IP resource boards to cover your needs.
Important:
You must add the SIP Trunk service provider’s IP address to the IP Device Range in Enterprise
Manager and select the proper codec profile for this service. See “Assigning Codec Profiles to
IP Addresses” on page 317. Failure to do this step may cause no voice path, even if the SIP
Trunk channel shows the call is connected.
