[Linphone-users] Free linphone.org SIP service not working?

[Martin Glaser]

Hi,

when I try to call my account (from Linphone on iOS), no connection can be 
established. There is only silence. Yesterday a connection was established, but 
"busy" signalled.

While registering from Linphone (iOS) works, I have trouble to register from 
Asterisk: 

[Jul 16 21:12:12] ERROR[907] tcptls.c: Unable to connect SIP socket to 
37.59.51.72:5061: Connection refused
[Jul 16 21:12:32] NOTICE[902] chan_sip.c:    -- Registration for ... timed out, 
trying again (Attempt #2)

When I check my logs I see that this problem started already 29th of June and 
since then it looks like Asterisk was not able to register anymore.

What's wrong?

Best Regards 

 Martin
