• RFC 2833 for DTMF tone delivery
• SIP MD5 authentication with SIP registration
• If AltiServ is behind NAT, verify that your SIP SP can support this configuration.
When subscribing to SIP Dial Tone service, typically your service provider will provide
you with the information required in the configuration dialog box shown in Figure 82.
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 305. Failure
to do this step may cause no voice path, even if the SIP Trunk channel shows
the call is connected.
