Sir,

To make it properly I allowed all ports on Cisco ASA I have one to one static NAT.

 

 

My ASA config

To allow polycom device from internal to outside

nat (inside) 10 10.1.1.247 255.255.255.255

access-list inside_access_in line 64 extended permit ip host 10.1.1.247 0.0.0.0 0.0.0.0

To allow polycom device from outside to inside
static (inside,Outside) 1.1.1.1 10.1.1.247 netmask 255.255.255.255
access-list Outside_access_in line 41 extended permit ip 0.0.0.0 0.0.0.0 host 1.1.1.1

 

Polcyom Device Config

On Polycom Device

NAT Configuration: Manual

Fixed Ports Checked

NAT Public WAN IP adresss: 1.1.1.1 ( Fictitous IP)

NAT h323 is compatible: Turned Off.

I do not belive that the Cisco ASA firewall is H.239 compatible. In your HDX system you can disable H.239 under Admin Settings > Network > Call Preferences. We had a problem with one of our previous units. Hope this Helps! 

Spoiler
It does help 🙂

Nothing to do with the ASA; your ports are correct. The Plycom firmware NAT implementation is botched. DISABLE all NAT configuration on the Plycom end-point; configure it as if there IS NO NAT; that means NAT is disabled; no public IP none of this; just simple static private IP and keep the ASA configuration as it is

 

I bet you a dollar that will work like a charm. I spent about an hour trying to use the Polycom NAT configuration until it was clear that it's the culprit. The ASA will do all required translations and Polycom will be completely unaware it is behind NAT. And yes you will be able to accept incoming calls from the outside
