Hi James,


It could depend on the network you have. It does not work in our network too, but we know from our provider that he closed all VoIP related ports. So we do not have a chance with this network. But… probably we can have some chance with TLS – need to try it out.


With Best Regards,

Hi All,


I am using flexisip as my sip server and I have two mobile phone, I am trying to make sip call from one phone(with linphone app) to another phone(with linphone app).

It works fine when both phones are under the NAT, but when a phone connected to internet(without nat) by 4G, I can't here any voice/video after sip call has been created.

But it works fine when I use test.linphone.org as my sip proxy. I think there must be something that I don't know need to be added in flexisip.conf.

How do I fix my configuration? or is there anything I need to do?
