Polycom HDX 8000 - IP Call issue

[Anonymous]

Hi,

I have a Polycom HDX 8000 endpoint on which i am not able to make or receive calls over IP.

It was all working fine and stopped working all of a sudden.

I have a Sonicwall in the network before the polycom device reaches out.

when trying to make a call it doesnt go through and the circle on the bottom left just stays on the 1st grey quarter & doesnt proceed further.

Whereas when i receive a call i can see where is it coming from and when i accept, the circle on the bottom left of the screen turns green suggesting its connected but the opposite party or me cannot see / hear each other.

Need advise on this.

Regards,

Gopal

Hi there...

have a look at this thread here (answer from OvG)

1. Check Fixed ports

2. open all necessary ports in you firewall.in both directions (1720+range from HDX - check PDF here)

3. Forward this ports from external address you NAT to internal address of you HDX (In Netgear)

4. Nat Configuration - Manual

5. Specify External address of you NAT in NAT Configuration Field

6. Uncheck  Nat is H.323 Compatible

Please make sure you have check enable h.323 call option in endpoint to make possible ip calls
