I assume it is registered with GK2. Yes, in case it is registered under GK2. Hmm, from this I see, that GW2 has no chance to know if the call was previously accepted by GK2 (only in case there is token or any mark from GK2). I just wanted to find a simpler case, but looks like it's the same case, just in my case GW2 is a GNUgk. Your previouse idea [putting some access token into LCF] would need the ability to handle (or pass through) such tokens on the remote side, right? [which is not known - can be another type of GK]. What do standards say about such case? [Unfortunately I'm don't know h.323 into deep details] ZM> You can take a look at OSP protocol.

Yes, I noticed that openh323 has OSP support now, took a look for some overviews about OSP and it can be interesting. However using OSP in GK will require to use an OSP server as well, IMO. As far as I know, there is not any open-source OSP server (I only know TransNexus's implementation which I guess is not open-source, maybe some client parts?). (good old days when we used as5300 with OSP :) ZM> In general, any method with a single token and a single auth ZM> server should allow such calls (maybe H.501 can do that too, ZM> like OSP). OSP is a fairly standard protocol and seems to become ZM> widespreaded in carrier networks. I will look again for OSP and maybe for H.501 as well. Thanks for suggestions and ideas!
