Dear All, I am using asterisk 1.4.21.2. I have used Originate manager application to to call the two persons. I have called AGI application to call another person. There I have used GET FULL VARIABLE AGI command to get the value. I am able to call another person form AGI. But when one end cut the call another one didn't disconnected. The following errors are displayed in Asterisk console, [Feb 8 11:12:16] ERROR[4115]: chan_sip.c:15553 sipsock_read: We could NOT get the channel lock for SIP/700-081da948!
