isdn lan only

Hi all,

Was wondering if there is a way make an H.323 endpoint work through the LAN only , through an isdn port. I do not want to use pstn.

Yes, as the link I've sent, you would connect to the router via ISDN and the router would transit the call over IP to another H.320 endpoint, ISDN or IP. Shold also be possible to interoperate with SCCP endpoint if you have CCM or CCME.

H.323 is for voice. Do you mean H.320? If so yes, you can connect via ISDN:

Re: isdn lan only

Yes, I meant H.320. Thanks for your reply. The link was helpful but wasn't what I was looking for, I apoligize I may have worded my question poorly.

I'm trying to find out whether or not I can use an ISDN H.320 device for local use only.

Lets assume my network had no connectivity to outside world or pstn.

Some H.320 endpoints do not support normal LAN connections, and only can use ISDN.

Thanks in advance!
