Hi All, XX-4849 provides the support for per-user forward timer due to which User call forwarding screen provides a field where the user can specify how long his phone should ring before the call gets forwarded to his voicemail box OR to the configured forwarding number. The default value being 20 seconds.  The question is where does this field get the value 20 seconds from ? Is this a default value assigned to this field OR is this value got from the "Default serial fork expiration" (default value = 20 seconds) If the "per-user forward time" is got from the "Default serial fork expiration", then changing the Default serial fork expiration should change the "per-user forward time" for users who have not configured this field , or atleast for new users added. (This does not happen as of now) If the "per-user forward time" is NOT got from the "Default serial fork expiration" then where is the Default serial fork expiration used ? Why do we need this parameter? It comes into picture when "huntgroup with call forwarding" , "huntgroup with fallback destination as another huntgroup" is used. Can someone please throw more light into this? If "huntgroup with callforwarding " is configured as follows: initially call---220---expiration=30 if no response --221--expiration=30 enable only the 'allow callforwarding' checkbox Set callforwarding for user 221 as follows : extension 221 will ring first for 5 seconds Always, Enabled, "if no response" forward to 224 ring for 30 seconds NOTE:-- here the per-user forward time for 221 is 5 seconds and the "default serial fork expiration" is 55 seconds Now call the Huntgroup extension --->user 220 rings for 30 seconds, upon no answer user 221 rings for 20 seconds and call is forwarded to 224 which rings for 10 seconds and the call gets disconnected. --Here the question is why 221 rings only for 20 seconds? Which parameter is a value of 20 referring to? Its neither the 'per-user forward time' nor the 'default serial fork expiration' . Please let me know if I have missed out something. Note: In the above scenario , if the "default serial fork expiration" is changed to 10 or 55 , the user 221 rings only for 20 seconds and then forwards the call to 224 Once the INVITE for 221 was sent to the registrar and registrar sends a 302 moved temporarily, I could see the following lines in the sipXproxy.log:-- 2009-07-10T06:51:51.802303Z:10829:SIP:DEBUG:jupiter.qantom.int:SipClientTcp-18:B65F1B90:SipXProxy:sipXproxymain::userCfwdTimeCallbackurl=<sip:[email protected]>;user=phone tmr=20 2009-07-10T06:51:51.802318Z:10830:SIP:DEBUG:jupiter.qantom.int:SipClientTcp-18:B65F1B90:SipXProxy:SipUserAgent::getUserSerialExpiresSeconds user=sip:[email protected];user=phone time=20 2009-07-10T06:51:51.802362Z:10831:SIP:DEBUG:jupiter.qantom.int:SipClientTcp-18:B65F1B90:SipXProxy:SipTransaction::recurseDnsSrvChildren transaction 0xb60db880 setting timeout 20 secs.
