Objective

Session Initiation Protocol (SIP) is a signaling protocol used to control multiple media communication sessions. SIP creates, manages and terminates sessions in an IP based network. SIP trunking facilitates private branch exchange to the Internet through the use of Voice over IP (VoIP). SIP trunking parameters on SPA8000 include proxy debug option and hunt policy. Proxy debug option controls which proxy debug messages are logged. The hunt group refers to a group of phone extensions that are organized to process specific calls. An incoming call can be forward to any member of a selected hunt group through the use of a specified algorithm. Multiple hunt groups are generally used to manage multiple incoming calls. The objective of this article is to configure SIP trunking parameters on the SPA8000 Phone Adapter.

Applicable Device

- SPA8000

Software Version

- 6.1.12

SIP Trunking Configuration

Step 1. Log in to the web configuration utility as an administrator and choose Advanced > Voice > SIP. The SIP page opens:

Step 2. In the Trunking Parameters area, choose an option from the Policy Debug Option drop-down list. The trunk parameters are Option, Notify, and Register. Option is the parameter that sends and receives optional response or request. Notify is the parameter that provides notification regarding response and request. Register is the parameter that registers the response and request received.

- None — This option allows no logging to occur. This is the default setting for proxy debug option.

- 1 - line — This option allows the start-line to be logged only for messages.

- 1 - line excl. OPT — This option allows the start-line to be logged for messages except OPTIONS response/request.

- 1 - line excl. NTFY — This option allows the start-line to be logged for messages except NOTIFY response/ request.

- 1 - line excl. REG — This option allows the start-line to be logged for message except REGISTER response/request.

- 1 - line excl.OPTINTFYIREG — This option allows the start-line to be logged for messages except OPTIONS, NOTIFY, and REGISTER response/request.

- full — This option logs all the SIP messages in full text.

- full excl. OPT — This option logs all the SIP messages in full text except OPTIONS response/ request.

- full excl. NTFY — This option logs all the SIP messages in full text except NOTIFY response/request.

- full excl. REG — This option logs all the SIP messages in full text except REGISTER response/ request.

- full excl. OPTINTFYIREG — This option logs all the SIP messages in full text except OPTIONS, NOTIFY, and REGISTER.

Step 3. In the Trunking Parameters area, choose an option from the Hunt Policy drop-down list. Hunt is the process of pursuing incoming calls that are applicable to the respective hunt policy chosen.

- Onhook only — The Hunt includes only the phones that are on hook state.

- Any state — The Hunt includes all phones regardless of the state.
