Description

Different behaviour of rtpengine_manage depending on where it is called

1. Response 180 is not sent to rtpengine :12221 using only reply_route
2. Response 180 is sent to rtpengine :12221 using onreply_route[MANAGE_REPLY]

Scenario 1 - reply_route only

• call rtpenginge_manage() in reply_route for responses
• works for 200 OK
• for 180 Ringing, the command does not appear on the wire to rtpengine :12221

Scenario 2 - reply_route is empty, use onreply_route[MANAGE_REPLY]

• call rtpenginge_manage() in onreply_route[MANAGE_REPLY]
• works for 200 OK
• for 180 Ringing, the command appears on the wire to rtpengine :12221, and SDP is injected

Troubleshooting

Reproduction

1. Confirmed that setup is working without onreply_route[MANAGE_REPLY]
2. Caller does not see any SDP inside 180 response; this means that rtpengine_manage decided not to end anything to rtpengine :12221
3. Move call to rtpengine_manage() inside onreply_route[MANAGE_REPLAY]
4. Now observe that SDP appears inside 180 response, indicating that rtpengine_manage decided that it should send the "offer" command to rtpengine :12221
