Text-GUI Features
Cisco BTS 10200 supports SIP client/handset
Cisco BTS 10200 provides complimentary support to SIP clients/handsets to update end user feature access status on the switch network database.
Provisioning in this context refers to feature activation or deactivation, and setting any applicable Directory Numbers (DNs) associated with the feature. If a SIP handset is used, the phone’s LCD panel is used as a menu display area to guide the user toward feature provisioning. If a SIP software client is used, the UI display region in the client software is used to guide the user through feature provisioning.
There may be multiple lines on the SIP phone, but currently services configured using softkeys on the phone are only available to one of those lines. The subscriber for that line is provisioned by
Cisco BTS 10200 with the MAC address of the phone (see “MAC to Subscriber” section on page
Supported Handsets
Cisco BTS 10200 supports any SIP client/handset that supports CallManager XML 3.0.
