SIP gateway, you can enter more parameters here.
¤

Codecs
(provider-dependent) The voice quality of VoIP connections is dependent on
the voice codec used for data transmission, and so the bandwidth of your DSL
connection (the better the codec the more data needs to be sent).
¤
Enable the voice codecs to be used by the gateway
Observe the specifications from your provider.
Priority when using codecs: from left to right, and top to bottom.
Allowed IP subnet
Specify the subnets to which calls are allowed.
Default: 0.0.0.0/0 all subnets are allowed
Format: IP address / subnet mask
The subnet mask determines how many bits of the IP address specified are
included:
32 All bits are included
Example: 192.168.1.1/32, only IP address 192.168.1.1 may be called
24 The first 24 bits are included
Example: 192.0.2.0/24, all IP addresses in network 192.0.2.* may be called
16 The first 16 bits are included
Example: 192.168.0.0/16, all IP addresses in network 192.168.*.* may be
called
8 The first 8 bits are included
Example: 192.0.0.0/8, all IP addresses in network 192.*.*.* may be called
