I have the same problem:
Test environment: LAN 170.0.1.0/24
Asterisk PBX: 170.0.1.131, 3CXphone1 on number 101, 3CXphone2 on number 105
on each desktop a USB camera, the local camera works.
From each 3CXphone debug window I got following lines:
Desktop 1: Calling 3CXphone 105:
---------------------------------------
Video stream will be received on 170.0.1.63:40004 <----- Port 40004 is identical with Softphone 105
No video port provided by remote party <----- Error Message
Desktop 2: Call from 3CXphone 101 to 105 accepted:
-------------------------------------------------------------
Video stream will be received on 170.0.1.150:40004 <----- Port 40004 is identical with Softphone 101
On both desktops firewall and antivirus are off,
Asterisk PBX is configured with 'NAT allways on', otherwise no communication with external line numbers are possible.
I got the same situation testing two X-Lite4 softphones insteed.
Thanks for any idea,
