Thanks, great.. Tjapko. -----Original Message----- From: openh323gk-users-admin@xxxxxxxxxxxxxxxxxxxxx [mailto:openh323gk-users-admin@xxxxxxxxxxxxxxxxxxxxx]On Behalf Of Zygmuntowicz Michal Sent: Viernes, 27 de Febrero de 2004 02:57 p.m. To: openh323gk-users@xxxxxxxxxxxxxxxxxxxxx Subject: Re: Interoperability Issues I'll include the fix soon as an optional feature. PS to Craig: this issue is partially addressed by the OpenH323 stack. In addition, it should not send empty Facility with H.245 tunneled message when communicating between >=V4 endpoints. Instead it should use Facility_UUIE with reason set to transportedInformation. But the gatekeeper in routed mode should have an option to translate Facility messages carrying H.245 tunneled elements (body: empty->facility(transportedInformation) and facility(transportedInformation)->empty) to ensure that older (probably badly designed and not checking Facility reason) H.323 implementations understand the purpose of Facility sent. ----- Original Message ----- From: "iTS Consult@ncy" <itsc99@xxxxxxxxx> Sent: Thursday, February 26, 2004 9:24 PM > My question is if this can or should be applied to gnugk like some > autosensing feature without having to guess why your calls get disconnected > when dealing with non v4 complient endpoints under certain circumstances. > ( tunneled) > > I have made my fix but outsite gnugk and simply would like to know if it can > be more transparent and for everyone who is using gnugk.
