SIP Phone Initialization

SIP Phone Initialization

Figure 2-1shows an example of SIP phone initialization on bootup, that is, how a typical phone might initialize itself and establish its identity with the BTS 10200.

The image shows actions that occur external to the BTS 10200—It does not show how the BTS 10200 controls SIP initialization. Instead, it shows how a client can establish its identity with the BTS 10200.

The circled numbers in the image indicate the numerical order in which the sequence occurs.

Provisioning a SIP Subscriber

To provision a SIP subscriber, see the “SIP Subscriber Provisioning” chapter in the Provisioning Guide.

SIP Registration and Security

SIP subscribers use the SIP REGISTER method to record their current locations with the BTS 10200. Registering clients can specify an expiration time for the contacts being registered. However, the BTS 10200 has a minimum and maximum acceptable duration, both of which are configurable.

Note Third-party registration is not supported.

It is possible to register multiple contacts for a single AOR; however, if multiple contacts are registered for a single subscriber, the BTS 10200 uses only the most recently registered contact to deliver the call to that subscriber. For this reason, multiple contacts are not supported.

Note Only one contact should be registered for an AOR.
