5. SIP Integration Factors
CODECs
The NetLink e340/h340/i640 Wireless Telephones are compatible with the G.711µ-
law and G.711a-law codecs. There is no setting required on the handset.
DHCP
Dynamic Host Configuration Protocol (DHCP) is a standardized protocol that
enables clients to be dynamically assigned with various configuration parameters,
such as an IP address, subnet mask, default gateway, and other critical network
configuration information. DHCP servers centrally manage such configuration data,
and are configured by network administrators with settings that are appropriate for a
given network environment. The handset will use the following DHCP options if
DHCP use is enabled:
Option Meaning
1 Subnet mask
3 Default gateway
6 DNS server
15 Domain name
66 TFTP server
151 NetLink SVP Server
152 NetLink OAI Gateway
siaddr Boot server or next server
DNS
Domain Name System (DNS), an industry-standard protocol, locates computers on
an IP-based network. IP networks rely on number-based addresses to move
information on the network. However, it is easier to remember friendly names than
number-based addresses, so it is necessary to translate user-friendly names into
addresses that the network can recognize. The handset will use DNS to automatically
translate names into IP addresses for the TFTP server and NetLink SVP Server.
In DHCP mode, the SIP handset will use DNS to look up an address for the logical
name “siptftp” to locate the SIP TFTP file server. If this logical name is undefined,
then the address specified by option 66 is used for the SIP TFTP server.
