Ok @miconda,
So let's start with the failover case first. I start a call on **kamailio1**: `kamcmd> dlg.list { h_entry: 2294 h_id: 5833 ref: 2 call-id: lbiUaRwZR8x3mRiBjxWlJDpqkO9JHTdD from_uri: sip:0409828030@proxy.alex.cloud.evox.it to_uri: sip:390409828030@proxy.alex.cloud.evox.it state: 4 start_ts: 1523361570 init_ts: 1523361570 end_ts: 0 timeout: 1523361757 lifetime: 187 dflags: 643 sflags: 0 iflags: 1 caller: { tag: 2Qp.E4ft3KpSHWbjfHVMI2Q3Jz0wEyxW contact: sip:0409828030@172.16.21.38:55236;ob cseq: 1646 route_set: sip:172.22.2.58;lr=on;ftag=2Qp.E4ft3KpSHWbjfHVMI2Q3Jz0wEyxW;did=6f8.6b92 socket: udp:172.22.2.57:5060 } callee: { tag: as47e134c0 contact: sip:39390409828030@172.16.201.101:5060 cseq: 0 route_set: sip:172.22.2.58;lr=on;ftag=2Qp.E4ft3KpSHWbjfHVMI2Q3Jz0wEyxW;did=6f8.7b92 socket: udp:172.22.2.57:5060 } profiles: { } variables: { { ru: sip:39390409828030@carrier1.cloud.evox.it } { du: sip:172.22.2.58:5060 } { cgrSupplier: carrier1.cloud.evox.it } { cgrSuppliers: carrier1.cloud.evox.it,carrier2.cloud.evox.it,carrier3.cloud.evox.it } { cgrCallip: 172.16.21.38 } { cgrDestination: 39390409828030 } { cgrAccount: 0409828030 } { cgrTenant: evox.it } { cgrReqType: *prepaid } { calleeNumber: 39390409828030 } { au: 0409828030 } { authType: subscriber } { cgrSubsystems: "cgr_subsystems":"*resources;*suppliers;*accounts" } { originalSourceIP: 172.16.21.38 } } }`
I then kill the **kamailio1** and start a new node **kamailio2** with empty dispatcher list. The call is still going on... now client side I do end the call that sends a bye to **kamailio2**, so the new kamailio node does this: `# ----------------------------------------------------------------------------- # route FOREIGN_DIALOG # short description # ----------------------------------------------------------------------------- route[FOREIGN_DIALOG] { $var(breadcrumbs) = "FOREIGN_DIALOG"; BREADCRUMBS
xlog("L_NOTICE","[f:$fU-t:$tU id:$ci | $rm] Foreign dialog detected for Call-ID: $ci\n");
dlg_db_load_callid($ci); setflag(FLG_AUTH_PASSED);
if (is_method("BYE")) { route(CGR_CALL_END); sl_send_reply("200","OK"); } exit; } # end route FOREIGN_DIALOG`
After the call has ended I have this in the dialog inside the kamailio2 node:
`kamcmd> dlg.list { h_entry: 2294 h_id: 5833 ref: 2 call-id: lbiUaRwZR8x3mRiBjxWlJDpqkO9JHTdD from_uri: sip:0409828030@proxy.alex.cloud.evox.it to_uri: sip:390409828030@proxy.alex.cloud.evox.it state: 4 start_ts: 1523361570 init_ts: 1523361632 end_ts: 0 timeout: 1523361758 lifetime: 188 dflags: 0 sflags: 0 iflags: 1 caller: { tag: 2Qp.E4ft3KpSHWbjfHVMI2Q3Jz0wEyxW contact: sip:0409828030@172.16.21.38:55236;ob cseq: 1646 route_set: sip:172.22.2.58;lr=on;ftag=2Qp.E4ft3KpSHWbjfHVMI2Q3Jz0wEyxW;did=6f8.6b92 socket: } callee: { tag: as47e134c0 contact: sip:39390409828030@172.16.201.101:5060 cseq: 0 route_set: sip:172.22.2.58;lr=on;ftag=2Qp.E4ft3KpSHWbjfHVMI2Q3Jz0wEyxW;did=6f8.7b92 socket: } profiles: { } variables: { { originalSourceIP: 172.16.21.38 } { cgrSubsystems: "cgr_subsystems":"*resources;*suppliers;*accounts" } { authType: subscriber } { au: 0409828030 } { calleeNumber: 39390409828030 } { cgrReqType: *prepaid } { cgrTenant: evox.it } { cgrAccount: 0409828030 } { cgrDestination: 39390409828030 } { cgrCallip: 172.16.21.38 } { cgrSuppliers: carrier1.cloud.evox.it,carrier2.cloud.evox.it,carrier3.cloud.evox.it } { cgrSupplier: carrier1.cloud.evox.it } { du: sip:172.22.2.58:5060 } { ru: sip:39390409828030@carrier1.cloud.evox.it } } }`
This stays in memory on the node and in the DB for 2 minutes after the call has ended and then it is cleared. Is this behaviour correct? Am I clear enough or do you want me to make a video of what's going on? Kind regards, Alex
