Major Differences Between 9600 Series SIP IP and 9600 Series H.323 IP Telephones

Review this section if your administrative environment includes both SIP and H.323 signaling protocols for 9600 Series IP Telephones.

General IP Telephony - Two major protocols handle Voice over IP (VoIP) signaling, Session Initiation Protocol (SIP) and H.323. The two protocols provide connection control and call progress signaling, but in very different ways. These protocols can be used simultaneously over the same network, but in general, no endpoint supports both protocols at the same time. Neither protocol is necessarily superior, but each offers some unique advantages. SIP telephones, for example, do not require centralized call servers, and can route telephone calls when a URL identifies the destination. H.323 telephones leverage the call server’s presence into the potential availability of hundreds of telephone-related features that a standalone SIP telephone cannot provide.

Signaling - 96xx Series IP Telephones ship from the factory with H.323 signaling. To use the SIP protocol, applicable H.323 96xx Series IP Telephones must be appropriately converted and configured. See the Avaya one-X™ Deskphone Edition for 9600 Series SIP IP Telephones Installation and Maintenance Guide for detailed conversion/configuration information.

Avaya Communication Manager Release - 9600 Series SIP IP Telephones are supported only by Communication Manager Release 4.0 and greater. SIP telephones use Avaya OPS (Outbound SIP Proxy) features on the “trunk” side of Avaya Communication Manager whereas the H.323 (IP) telephones are supported on the “line” side of the Communication Manager. When a 9600 Series SIP IP Telephone is running under Communication Manager Release 5.0, an additional feature, Extend Call, is available.

Required Servers - SIP 9600 Series IP Telephones use two [additional] servers that H.323 telephones do not:

-SIP Proxy server - provided by SIP Enablement Services (SES) software, and

-Network Time server - which controls time-related parameters.

These servers are not necessarily separate hardware units.

Features & Functions supported by H.323 9600 Series IP Telephones, Not Supported by SIP - Button modules are not currently supported by 9600 SIP IP Telephones.

Backup/Restore - 9600 Series (H.323) IP Telephones use HTTP to store backup files. 9600 Series SIP IP Telephones use the Personal Profile Manager (PPM) functionality within SIP Enablement Services (SES) for backup and restore functions.

Settings File & System Parameters - Both SIP and H.323 9600 Series IP Telephones (and 4600 Series IP Telephones) use the same settings file. Some of the same system parameters are used, however, numerous SIP-specific parameters support SIP operation only. In H.323 9600 Series IP Telephones, the parameters OPSTAT and APPSTAT control all user interface functions, whereas 9600 Series SIP IP Telephones use a separate parameter (for example ENABLE_CONTACTS, ENABLE_CALLLOG) for each user interface function.
