I agree that limitation of number of simultaneous calls should be done by radius server not gnugk. In that way you can combine different limitation methods: by calling endpoint, by group of endpoints belonging to one account, or even total numbers of all calls on that gatekeeper. Of course it is one or two extra database queries, but thats life :) Regards, Aivis -----Original Message----- From: openh323gk-users-admin@lists.sourceforge.net [mailto:openh323gk-users-admin@lists.sourceforge.net]On Behalf Of Zygmuntowicz Michal Sent: Thursday, December 18, 2003 12:40 PM To: openh323gk-users@lists.sourceforge.net Subject: Re: RadAliasAuth - Some thoughts E164 rewritting is a definitelly thing that should be implemented. It's on my todo list:) No. of concurrent calls can be calculated from DB and restricted by radius server + db, so I would rather not send it from the gk. But if you need this, you can easily build your own authenticator/acct module that derives from RadAuth/RadAliasAuth/RadAcct and overrides only one method (OnSendPDU) to include any attributes you wish:) ----- Original Message ----- From: "Nir Simionovich" <nirs@m-wise.com> Sent: Wednesday, December 17, 2003 11:10 PM > I've been fiddeling around with Radius lately, and got some really > neat results (Thanks Aivis from DataTechLabs - you rock).
