I have a repeated error in the asterisk console. Incoming call: Got SIP response 400 "Bad Request" back from 10.0.2.136 It is repeated every few seconds and never stops until I restart Asterisk. It starts after I make a call to a certain extension, 202 which transfers the call to another extension all phones then hang up. The SIP trace looks like: <-------------> --- (7 headers 0 lines) --- SIP Response message for INCOMING dialog BYE arrived -- Incoming call: Got SIP response 400 "Bad Request" back from 10.0.2.136 set_destination: Parsing <sip:vgp at 10.0.2.136:5060> for address/port to send to set_destination: set destination to 10.0.2.136, port 5060 Reliably Transmitting (no NAT) to 10.0.2.136:5060: BYE sip:vgp at 10.0.2.136:5060 SIP/2.0 Via: SIP/2.0/UDP 10.0.4.147:5060;branch=z9hG4bK4c02bc4f;rport From: "Paul" <sip:paul at 10.0.4.147>;tag=as1ed7b694 To: <sip:paulxfertest at middlesborough.kainos.com>;tag=C1431100-8D08-9097-2513 -8F10A9A44C48 Call-ID: 5b3c1b093ca08aa83b9a99cc128033c9 at 10.0.4.147 CSeq: 299 BYE User-Agent: Asterisk PBX Max-Forwards: 70 Content-Length: 0 --- Scheduling destruction of SIP dialog '5b3c1b093ca08aa83b9a99cc128033c9 at 10.0.4.147' in 32000 ms (Method: BYE) vmpccentos*CLI> <--- SIP read from 10.0.2.136:5060 ---> SIP/2.0 400 Bad Request Via: SIP/2.0/UDP 10.0.4.147:5060;branch=z9hG4bK4c02bc4f;rport From: "Paul" <sip:paul at 10.0.4.147>;tag=as1ed7b694 To: <sip:paulxfertest at middlesborough.kainos.com>;tag=C1431100-8D08-9097-2513 -8F10A9A44C48 CSeq: 299 BYE Call-ID: 5b3c1b093ca08aa83b9a99cc128033c9 at 10.0.4.147 Content-Length: 0 <-------------> --- (7 headers 0 lines) --- SIP Response message for INCOMING dialog BYE arrived -- Incoming call: Got SIP response 400 "Bad Request" back from 10.0.2.136 Does anyone have any idea what could be causing this?
