with suspend procedure is not supported.

 

 

 

 

 

Emergency Call (911) is supported for SIP endpoints with one caveat: If the

 

 

 

 

 

calling party (SIP subscriber) disconnects the call, the called party control is

 

 

 

 

 

not available. Otherwise, the call will be released. Expanded emergency

 

 

 

 

 

service (E911) does not require this, but basic emergency service (911) does.

 

 

 

 

 

Both 911 and E911 are supported for MGCP endpoints.

 

 

 

 

 

The Public Safety Answering Point (PSAP) is selected based on default user

 

 

 

 

 

location. No mobility is supported.

 

 

 

 

 

 

 

Anonymous Call Rejection

ACR

Same as MGCP, when provided by the BTS 10200. Also provided by the

 

 

 

 

 

phone.

 

 

 

 

 

 

 

Anonymous Call Rejection

ACR_ACT

BTS 10200 functionality is same for SIP subscribers as for MGCP.

phone.

 

 

 

 

 

 

 

Anonymous Call Rejection

ACR_DEACT

BTS 10200 functionality is same for SIP subscribers as for MGCP.

 

 

Deactivation

 

 

ACR_DEACT is also supported on some SIP phones. Depending on the

 

 

 

 

 

 

 

 

 

 

specific phone, the feature on the BTS 10200 might work jointly with the

 

 

 

 

 

feature on the phone.
