| Enable 100rel |

|
|
|
| The use of the PRACK (Provisional Acknowledgment) method enables reliability to SIP |
| |
|
|
| provisional responses (1xx series). This is very important in order to support PSTN inter- |
|

|
| networking. To invoke a reliable provisional response, the 100rel tag is appended to the |
|
|
|
| value of the required header of initial signaling messages. |
