Hello,

I use BigBlueButton, 0.81 and we must enable dial into conference via phone.
Several months ago everything was good (working), but now it  does not work ( I was working on thuesday for short time).
I use external SIP account and there is problem with registration .
There is error "2014-12-05 10:38:11.171892 [WARNING] sofia_reg.c:472 Bezposredni Failed Registration [503], setting retry to 60 seconds."

I have just tried in different networks, on different servers and with two independent SIP operators.
The usual voip client (X-Lite) is working ok with SIP accounts.

I have attached a detailed debug log in file freeswitch.log.

Please give any suggestions. I am in very difficult situation, because it is my work and I must repair it, but after several days I have no idea.

Thank you in advance.

Best regards,
Kamil
