The default SIP T timer values for GPRS bearer are 3, 16 and 17secs. The default SIP T timer values,for WLAN is 500ms, 4secs and 5secs. The read operation on SIP T timers is <i>alwayspass</i> and write operation requires <i>writedevicedata</i> capability. </p> <p>The central repository keys for SIP T timers and its CenRep UIDs are as follows: </p> <codeblock id="GUID-5FE5A016-F24B-5E49-AC60-A4502307740F" xml:space="preserve">
