Message Waiting Indicator <mwi/>
In the following table, x is the registration number. IP 301, 320, 330, 430: x=1-2;
IP 501: x=1-3; IP 550, 560: x=1-4; IP 600: x=1-6; IP 601: x=1-12;
IP 650, 670: x=1-34; IP 4000: x=1; IP 6000: x=1; IP 7000: x=1.
This configuration attribute is defined as follows:
Network Address Translation <nat/>
These parameters define port and IP address changes used in NAT traversal.
The port changes will change the port used by the phone, while the IP entry
simply changes the IP advertised in the SIP signaling. This allows the use of
simple NAT devices that can redirect traffic, but do not allow for port
mapping. For example, port 5432 on the NAT device can be sent to port 5432
on an internal device, but not port 1234.
