Hi guys, My asterisk didn't send ACK for 200 ok message just for one specific extension. The ATA used by this extension is used by other extensions, with same firmware version. Looking in wireshark, I saw that ATA sent 200ok and asterisk didn't confirm it with ACK. The ATA did this during 20s, after this, asterisk hangup the call. This issue happen only one asterisk start a call. I'm using the latest version of asterisk. What can be the source of this problem, and how can I debug this problem in asterisk ? Thanks.
