What are the Open Firewall Ports needed for Polycom HDX7000 Video Conference

I have a Watchguard Firewall Firebox X55e and I’m installing a Polycom HDX7000 video conference system.
The issue is regarding that in the local site (behind the X55) when a made a video call I can NOT see my client video however the other side CAN see me, reading some internet posts it seem to be a firewall issue but I just pen the ports and redirected to my HDX system but the issue remain.
Attached are the ports that I opened without success.

Plase your support... Thanks

Like mentioned in "Administrator’s Guide for Polycom® HDX™ Systems" http://www.nevis.columbia.edu/twiki/pub/Nevis/Videoconference/Polycom_HDX_Admin_Guide.pdf

Make sure that firewalls being traversed allow Polycom HDX systems
behind them to open outbound TCP and UDP connections.
— Firewalls with a stricter rule set should allow Polycom HDX systems
to open at least the following outbound TCP and UDP ports: 1720
(TCP), 14085-15084 (TCP) and 1719(UDP), 16386-25386 (UDP).
— Firewalls should permit inbound traffic to TCP and UDP ports that
have been opened earlier in the outbound direction.
