Hello,
For more than a year now on all three of my Opensips production proxies I've
seen the following errors from time to time:
WARNING:tm:w_t_reply: ACKs are not replied
ERROR:signaling:sig_send_reply_mod: failed to send reply with tm module
There were only a handful a day, and they didn't
Thanks Kennard and Stanislaw.
I've opted for the Stateful Registrar method for the moment, and
initial testing shows this does fix the error.
I created a page to detail a little more on the changes required here:
