Hi,
we have a setup with an Asterisk, an openser and a Cisco 5400 in place. Asterisk is the frontend to the users, providing registering and RTP proxy functionality and openser is the gate-keeper of the Cisco. I can call in and out, everything is fine so far. But there is one strange fact: when I place a outbound call (from a VoIP phone to the asterisk, from the asterisk to the openser, from the openser to the Cisco, from the Cisco into the PSTN) and cancel this call by hanging up the VoIP phone before the call was establish, I can see the correct message flow for a cancelation (Asterisk says CANCEL to openser, openser says "200 cancelling" to Asterisk, openser talks to the Cisco, finally openser says "487 Request cancelled" to Asterisk and Asterisk says ACK). So far so fine. But then, Asterisk says CANCEL again. With the same call-id, the same tags, just completely the same CANCEL as before. Why? I was under the impression, that it has correctly identified the messages from openser, since it has answered with ACK. I've already compared this message-flow to the one of the other direction (inbound call, cancelled from PSTN phone), which correctly ends with the ACK. I can not find any significant difference. I've attached on ngrep trace. 212.153.11.54 is asterisk, 212.153.11.19 is openser and 146.188.127.31 is the Cisco. Can anyone give me any hint? Thanks, Wolfgang
