Hi Roger, Apparently there is some protocol specifying that when the message is too large, the network should use TCP instead of UDP, so let’s focus on debugging the TCP. I have always registered my client to use TCP and expect it to work.
Just to clarify, the logging you sent is from Bono node? Would you turn on debug logging and send a more detailed log? Also if you can do a tcpdump on Bono it will be helpful as well. Thanks!

UDP registration/Invite from UE works fine, but an Invite to UE is too big. Where can I find the meaning of various log messages, such as: 15-12-2017 00:38:09.962 UTC Error pjsip: tcpc0x7f095455 TCP connect() error: Connection refused [code=120111] And 15-12-2017 00:46:27.070 UTC Status sip_connection_pool.cpp:447: Recycle TCP connection slot 9 And 15-12-2017 00:46:49.225 UTC Status alarm.cpp:62: sprout issued 1004.1 alarm 15-12-2017 00:46:49.225 UTC Status alarm.cpp:62: sprout issued 1001.1 alarm 15-12-2017 00:46:49.225 UTC Status alarm.cpp:62: sprout issued 1002.1 alarm Thanks!

So if the client registered as TCP, Bono would be forwarding TCP messages. As for topology hiding, no Bono doesn’t do it. Thanks, Ying From: Clearwater [mailto:[email protected]] On Behalf Of Roger Case Sent: 08 December 2017 20:14 To: [email protected]<mailto:[email protected]> Subject: [Project Clearwater] Bono Send Invite using TCP, Header Reduction Dear Clearwater, The PacketCable 2.0 eDVA UE endpoints I am using will not send responses to Invites if the response is greater than 1300 bytes, and it wants to respond using UDP. Is there a way to get Bono to send the Invite to the UE using TCP? These devices should then respond using TCP. Also, the Bono P-CSCF includes all Record Route and Via headers for the call. Is there a way to reduce the number of headers sent to the UE, making the Invite smaller? Can Bono do a bit of topology hiding, to accomplish this? Thanks very much. Roger Case GCI Alaska
