5i Series IP Phone Release Notes

Ability to Remove UserAgent and Server SIP Headers

Currently, the phone always configures the SIP UserAgent/Server headers to

contain:

Aastra <PhoneModel>/<FirmwareVersion>

A new feature has been added to Release 2.1 that allows an Administrator to

suppress the addition of these headers by using the following parameter in the

configuration files:

• sip user-agent

Setting this parameter allows you to enable or disable the addition of the

User-Agent and Server SIP headers from the SIP stack.

An Administrator can configure this feature using the configuration files only.

Configuring UserAgent/Server SIP Headers

You use the following parameter to specify whether the UserAgent and Server SIP

header is added to the SIP stack.
