Hi,<br><br>>I think ser should remember canceled transactions and send CANCEL in <br>>case of delayed provisional replies.<br><br>At present I don't think its working like this, As soon as CANCEL hit SER an immediate too many hops is returned to sender and call continues....resulting in ghost call, where A party has dropped after sending cancel and B still carries on as no cancel was sent to B.<br><br>Best Regards,<br>Abdul Qadir<br><br><b><i>Klaus Darilion <klaus.mailinglists@pernau.at></i></b> wrote:<blockquote class="replbq" style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;"> Abdul Qadir wrote:<br>> Hi , <br>> <br>> I tried to call from one nokia sip (E61 and other models )phone to another nokia sip phone. The call works fine. The problem comes only when I call from Phone A to Phone B and then immediately cancel the call(from Phone A). The Phone A will hangup the call as it sent CANCEL but the SER will ignore
this CANCEL and still send INVITE to Phone B resulting in a ghost call situation.<br>> <br><br>Hi!<br><br>I think ser should remember canceled transactions and send CANCEL in <br>case of delayed provisional replies.<br><br>regards<br>klasu<br><br>> I tried to capture a log of message and found that Phone A "CANCEL" message is received on SER even before any provisional response from Phone B. Therefor SER doesnot relay this CANCEL request to Phone B. I even checked RFC which clearly says that UAC should not send CANCEL untill it receives any provisional response. I talked to Nokia expert and they said the 100 Trying message from your server is considered as provisional response, therefor behaviour of client is absolutely correct.<br>> <br>> Is there any way I can stop 100 Trying message and still run statefull SER, so that I can verify what nokia said. Any ideas suggestions are welcome.<br>> <br>> Thanking you all in advance.<br>> <br>> Best
