[OpenSIPS-Users] Sometime opensips sends 477 reply for BYE packet in TLS

[Vinayak Makwana]

Hello all,
I am facing an issue when opensips gets BYE from the freeswitch side. At
that time, opensips sent 477 reply to the BYE request.

Here's the call scenario : when we dial the call from softphone to
opensips, it's TLS call flow, and from opensips to Freeswitch, it's UDP
call flow. So when we disconnect a call from Softphone at that time, the
call disconnects properly, but when we disconnect a call from FreeSwitch at
that time, opensips sends 477 sending failed to Freeswitch. but sometimes
OpenSIP sends 200 OK successfully to Freeswitch, and calls get disconnected
also.

*opensips logs at the time of 477 reply send:*
 ERROR:core:tcp_connect_blocking_timeout: connect timed out, 99171 us
elapsed out of 100000 us
 ERROR:core:tcp_sync_connect_fd: tcp_blocking_connect failed
 ERROR:proto_tls:proto_tls_send: connect failed
 ERROR:tm:msg_send: send() to a.b.c.d:53722 for proto tls/3 failed
 ERROR:tm:t_forward_nonack: sending request failed
 DBG:tm:t_relay_to: t_forward_nonack returned error
 DBG:sl:sl_reply_error: error text is Send failed (477/SL)

Please suggest if anything needs to be configured on the opensips side.
