[OpenSIPS-Users] Problem with force_send_socket

[Olle Frimanson]

Hi , we are using Opensips 2.3.3 and have a setup with 

 

UAC- Edge Proxy - Registrar - Freeswitch

 

Clients connect using TLS and we use UDP for internal communication.

 

Edge proxy use force_send_socket(udp:172.27.251.4:5070) and all have been
fine even for packets of around 1700 bytes.

 

Now we have installed the system in a new environment and have started to
see MTU problems and we want to switch to TCP for the internal
communication.

 

We have switched to setting the sent socket to tcp:
force_send_socket(tcp:172.27.251.4:5070) but this fails.

 

We listen on the same port on both UDP and TCP.

 

With debug logging this is the only output:

2018-03-22T16:58:50.517287+00:00 err sipedge-qa-1 ERROR:tm:msg_send: send()
to 172.27.251.4:5070 for proto tcp/2 failed

2018-03-22T16:58:50.517669+00:00 err sipedge-qa-1 ERROR:tm:t_forward_nonack:
sending request failed

 

Any ideas?

 

Thanks in advance / Olle
