• Domain – The Domain Name of the SIP Trunk service provider, if required.
• SIP Register Period – How frequently the AltiGen system needs to send SIP reg-
istration packets to the service provider. This can detect if the service provider is up
or not. Some service providers do not accept SIP Register messages. In these cases,
you can disable sending SIP Register messages from AltiServ by setting the SIP
Register Period to 0.
• SIP Trunk Profile – Select the appropriate SIP trunk profile. (See “Creating a SIP
Trunk Profile” on page 147.)
• SIP Source Port – For SIP UDP, select the source port from 5060 or 10060. For TCP
or TLS, you cannot change ports. Using a port other than 5060 will prevent SIP-ALG
firewall/router from changing the SIP packets.
• SIP Destination Port – A SIP Trunk can have different source port and destination
port.
• Automatic NAT Traversal – Leave this box unchecked.
• Enable Channel – After all above parameters are entered correctly, check this box
to activate the channel. The system will send authentication to the service provider
to verify the setting.

To delete a row, select it and click Delete.
Creating a SIP Trunk Profile
Different SIP service providers may support different ways of sending a caller ID. To
provide callees with a more accurate caller ID, you can create a SIP Trunk Profile for a
particular service provider, when necessary. Otherwise, a default profile is used. Once
you have created a profile, you can select it in the SIP Trunk Configuration Edit box (see
Figure 82).
To create a SIP Trunk Profile, in the SIP Trunk Configuration dialog box shown in
Figure 82, click the SIP Trunk Profile button on the right.
