<div class="PlainText">Hello eyas,<br>
The NAT issue in IMS (and VoIP) solution networks, is affected to<br>
user-plan (e.g Voice) only. In this regards, you maybe have no-way<br>
audio or one-way audio.<br>
As you mentions, Your isuue is in control-plan (signalling in IMS),<br>
Then it is not regards of NAT issue.<br>
Please check your network again. also check mediation devices between<br>
p-cscf and user2's device, so that why the user2 doesn’t receive<br>
INVITE signalling.<br>
Do you could use Multi-Homed in p-cscf or not?<br>
With Regards.Mojtaba<br>
