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

[Martin Glaser]

I also think that asterisk is not doing SRV queries, because in that case it 
would use also the port given there (5223 or 443), wouldn't it? But the error 
message clearly says that asterisk is trying to reach 37.59.51.72:5061. So that 
must come from somewhere else. Or maybe there is guesswork going on in the form 
"if you can't reach what is in DNS then try the default port, maybe that works".

Best Regards

 Martin
