Calling Using the H.323 Protocol

Polycom VVX 500 and VVX 600 Business Media Phones and Polycom VVX Camera User’s Guide

Note: Audio-Only Calls and H.323

Placing audio-only calls applies to SIP calls only. This feature is not available for H.323 calls.

Your system administrator can set up your phone so that it can handle calls that use either the SIP or H.323 protocol, or both protocols. When this feature is enabled, your system administrator can set up your phone so that you can select which protocol to use before you tap Dial or Send, or before a call is automatically placed. Your system administrator can also set up your phone so you can automatically select the protocol to use.

When your phone is set up to handle both protocols and your phone enables you to select a protocol to use before placing a call, select the protocol you want to use by one of the following methods:

∙Soft Key Method Soft keys display to allow you to choose the protocol. Tap Use SIP, to place a SIP call, tap Use H.323, to place an H.323 call, or tap Use Auto, to allow your phone to automatically select the protocol to use. Tap each soft key one or more times to toggle between them. The protocol you select displays in the title bar. Your phone uses the selected protocol for all subsequent calls, unless you select a different protocol.

∙Dialog Box Method A dialog box displays to allow you to choose the protocol. Tap Use SIP, to place a SIP call, or Use H.323,to place an H.323 call. For dual-protocol phones, the protocol displays next to all call IDs, including the call IDs for conference call participants and calls on hold. When you place calls from call lists or directories, your phone automatically chooses the protocol to use based on the information in the call list or directory. When you set up a contact in your local Contact Directory, you can specify the protocol the contact uses to handle calls. This allows your phone to automatically use the correct protocol when you dial the contact.

When your phone supports H.323 protocol the following limitations exist:

∙You cannot forward or transfer H.323 calls.

∙You cannot set up forwarding for lines that just use the H.323 protocol.

∙You cannot set up shared lines for lines that use the H.323 protocol.

∙You cannot place a call by just entering an H.323 name. To place a call using an H.323 name, use URL-dialing mode and enter the following format for the URL:

<H.323 name>@<server name>

For example: VVX101@100.100.100.100
