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?
James
