DIALING OUT VIA INTERNET

[Chet Cronin]

Running an C40 and trying to dial both the Polycom and CISCO test numbers via IP only (No gatekeeper)

In direct mode.

Getting the following error:

Could not place to h.323 64.102.241.236 (which is the CISCO test number)

Any ideas ... There is a firewall in the network.

Verified ports and 1719/1720 are open bi directional

Hi Chet,

Check ALG on your firewall. Disable ALG for H323.

Also refer to these list of ports for H323  standalone (direct):

Try this settings on the codec:

Configuration->Advance Configuration->H323->Profile 1->Callsetup Mode: Direct

Configuration->Advance Configuration->H323->Profile 1->PortAllocation : Static

Enable NAT mode on the codec:

Configuration->Advance Configuration->H323->NAT->Address : YOUR_NAT_ADDRESS

Configuration->Advance Configuration->H323->NAT->Mode: ON (Try also set to Auto if ON won’t work)

Regards,
