Configuring Restricted Access Domains

If you enter domains, the Cisco IP phones respond to SIP messages only from the
identified servers.
To configure restricted access domains, navigate to Admin Login > advanced >
Voice > System. Under System Configuration in the Restricted Access Domains
field. Enter fully-qualified domain names (FQDNs) for each SIP server you want the
phone to respond to. Separate FQDNs with semicolons. For example,
voiceip.com;voiceip1.com.

Configuring DHCP, Static IP, or PPPoE Connection Type

You can set the connection type to one of the following:
Description
To set the phone to communicate by using the remote
phone-preferred codec, select yes. If set to no, the Cisco
IP phone communicates by using its own preferred codec
(as indicated in the Preferred Codec field and in the SDP
by order of preferences). The default vale is no.
When set to Default, the Cisco IP phone responds to an
Invite with a 200 OK response advertising the preferred
codec only. When set to List All, the Cisco IP phone
responds listing all the codecs that the phone supports.
The default value is Default.
