[cisco-voip] TP EX90 one way video only

It's most likely the NAT that is causing the issue. You may need to turn on SIP inspection on the router so that it tries to replace the internal IP with the external IP. Without the inspection, the other unit will be sending video to the internal IP which it can't real.

Dear all

I have TP EX90 with real IP address; I tried to make video call with another TP
but we face an issue; they can see me but I can't

TP Ex90 ---> LAN ---->Router----> Internet <---- TP Ex90

I configured static NAT on router
//  ip nat inside source static 192.168.0.50 196.2XX.X.XXX

Is there any additional configuration to solve this issue??



Thanks
