Field Name Values Description

SIP Fields

Use Proxy Y/N Select if proxy server is used.

Transport

Protocol

TCP or

UDP

Voip administrator must choose

between UDP and TCP

transmission protocols. UDP is a

high-speed, low-overhead

connectionless protocol where

data is transmitted without

acknowledgment, guaranteed

delivery, or guaranteed packet

sequence integrity. TCP is slower

connection-oriented protocol

with greater overhead, but

having acknowledgment and

guarantees delivery and packet

sequence integrity.

SIP Port

Number

5060 or other

*See RFC3087

(“Control of

Service

Context using

SIP Request-

URI,” by the

Network

Working

Group).

The SIP Port Number is a

UDP logical port number.

The voip will “listen” for SIP

messages at this logical port.

If SIP is used, 5060 is the

default, standard, or “well

known” port number to be

used. If 5060 is not used,

then the port number used is

that specified in the SIP

Request URI (Universal

Resource Identifier).

SIP URL sip.userphone

@

hostserver,

where

“userphone”

is the

telephone

number and

“hostserver”

is the domain

name or an

address on the

network

Looking similar to an email

address, a SIP URL

identifies a user's address.

In SIP communications, each

caller or callee is identified

by a SIP url:

sip:user_name@host_name.

The format of a sip url is very

similar to an email address,

except that the “sip:“ prefix is

used.
