The first network in question, which to me the STUN server reveals as
PJ_STUN_NAT_TYPE_PORT_RESTRICTED, is below another network that STUN
shows as PJ_STUN_NAT_TYPE_SYMMETRIC.
So, I'm running tests using ICE enabled, without setting up a TURN
server, in an attempt to find them on the local network. However, I'm
noticing that when ICE is enabled, the INVITE gets to the SIP server
(Kamailio), but I can not figure out why the INVITE does not reach the
other endpoint.
The main problem I want to understand / solve in this case is the call
on the local network (which is below a symmetric NAT), using STUN,
because I will also receive calls outside this network, which
apparently is already working well.
Maybe it´s a simple problem, but I still can't understanded, Why does
audio not "travel" to endpoints on the same network (with symmetric
NAT) when STUN is enabled? Do I need a TURN server for audio to
traffic on the same network?
If anyone can help me,
Thanks.

Hello,
I'm using pjsua2 in conjunction with the classes and functions of pjlib for
an application. But I'm having a little problem, which I could not solve.
On the same specific network, I have two endpoints registered on a remote
SIP server (public ip). When they are set to use STUN, I can do / accept
INVITE, but the audio does not travel over the network. In the same
environment, if one of the endpoints is not using STUN, audio travels
normally. Another detail, with STUN enabled at both endpoints, if one of
these endpoints is on another network, audio travels normally.
However, in another network with the same characteristics
(PJ_STUN_NAT_TYPE_PORT_RESTRICTED) according to the STUN resolution, the two
endpoints "talk" normally.
Evaluating the firewall of this first network, I found nothing that could be
blocking this communication.
Comparing the pjsip logs to the Xcode console, I could not find any
information that could help me understand what's happening.
If anyone can help me,
Thank
