Understanding SIP Settings

The following list describes all SIP Settings on the IP Network screen.

• Enable SIP Mark this check box to enable the HDX system to receive and make SIP calls.

• SIP Server Configuration Select Auto if your Microsoft server (Lync or Office

Communications Server) configuration is set up for automatic discovery, which requires you to

correctly configure Lync SRV records. If Microsoft server (Lync or Office Communications

Server) is not configured for automatic discover, you need to select Specify.

• Server Name or IP Address If you selected Specify in the SIP Server Configuration field,

you need to specify the IP address or DNS name of the SIP Registrar Server.

○ In a Lync Server environment, specify the DNS name of the Lync Server. The default port

is 5061.

○ If registering a remote HDX system with a Lync Server edge server, use the fully qualified

domain name of the access edge server role. The port for the edge server role is usually

443 and must be entered explicitly.

○ You can also enter the name of a Lync Director Server.

Polycom recommends using the DNS name. The format for entering the address and port is

the following: <DNS_NAME>:<TCP_Port>:<TLS_Port>

Syntax Examples:

○ To use the default port for the protocol you have selected: lyncserver.corp.local

○ To specify a different TLS port (and use the default TCP port):

lyncserver.corp.local::443

Note: If you have not installed the RTV option key, this setting is named Registrar Server.

• Proxy Server Specify the DNS name or IP address of the SIP Proxy Server. If you leave

this field blank, the Registrar Server is used. If you selected Auto for your SIP Server

Configuration and leave the Proxy Server field blank, no Proxy Server is used.

By default for TCP, the SIP signaling is sent to port 5060 on the proxy server. By default for

TLS, the SIP signaling is sent to port 5061 on the proxy server.

The syntax used for this field is the same as for the Registrar Server field.

Note: If you have installed the RTV option key, this setting is hidden. In Microsoft networks,

the Proxy server and the Registrar server are always the same server, so only one server

address field is required.

• Transport Protocol The SIP network infrastructure in which your Polycom HDX system is

operating determines which protocol is required.

○ Auto enables an automatic negotiation of protocols in the following order: TLS, TCP, UDP.

This is the recommended setting for Microsoft environments.

○ TCP provides reliable transport via TCP for SIP signaling.

○ UDP provides best-effort transport via UDP for SIP signaling.

○ TLS provides secure communication of the SIP signaling. TLS is available only when the

system is registered with a SIP server that supports TLS. When you choose this setting,

the system ignores TCP/UDP port 5060. TLS is required when connecting to a Microsoft

Lync or Office Communications server.

• Domain Name Specifies the domain name for authentication with the LDAP server. You can

leave this field blank when you use a UPN (username@domainname.com) in the User Name

field (recommended).

• Sign-in Address Specify the system’s SIP name. This is the SIP URI. Specify the user

name for the conference room or user account created for the Polycom system.

Note: If you have not installed the RTV option key, this setting is named User Address.

• User Name Specifies the name to use for authentication when registering with a SIP

Registrar Server, for example, jsmith@company.com.

Polycom supports the User Principal Name format (username@domain.com) as well as the

legacy Microsoft DOMAIN\username format. If the SIP server requires authentication, this field

and the password cannot be blank.

Note: If you have not installed the RTV option key, this setting is named Domain User Name.

• Password When enabled, allows you to specify and confirm a new password that

authenticates the system to the SIP Server.

• Directory: Microsoft Lync Server Specifies whether the SIP Registrar Server is a Lync

Server. Enabling this setting activates integration features such as the Microsoft global

directory and Lync 2010 contact sharing with presence.
