Allocating a SIP Network Access Point (NAP)
(Applies to version(s): v3.0)
You must allocate a SIP NAP for your system. To create a new NAP:
Click Create New NAP
Create the new NAP:
- Enter a name for the NAP
- Click Create
Verify that the NAP was successfully created message appears
Associate a SIP transport server with the new NAP:
- Select a SIP Transport Server from the Available list
- Click "<<" to associate the SIP Transport Server with the NAP
Note: It is not recommended to use multiple SIP transport servers in one NAP, because NAP availability may be inconsistent if one of the transport servers is down. For redundancy, it's recommended to create two NAPs and create redundant routes that point to each NAP (using weighted load sharing, or priority routing, as required).
Enter proxy address:
Associate a Port range with the new NAP:
- Select a port range from the Available list
- Click "<<" to associate the Port range with the NAP
Note: The port range does not have to be on the same IP Interface than the SIP transport server.
Note: Multiple port ranges on different IP interfaces can be used for load-sharing or redundancy. Each call will be assigned a port from one of the ranges in a "load-sharing" manner.
[OPTIONAL] Associate SIP Domains with the new NAP:
- Select a sip domain from the Available list
- Click "<<" to associate the SIP Domain with the NAP
Configure settings for the following parameter groups as required:
- Registration Parameters
- Authentication Parameters
- Network Address Translation
- SIP-I Parameters
- Advanced Parameters
- Click Save
Since 3.0.103 you have the option to disable a NAP. A disabled NAP will refuse incoming SIP calls, and will not be used for outgoing calls.
