Hi all,
I have a question about the H450.3 Call Diversion recommendation when the gatekeeper handles the diversion.
Figure 12 in section 10 shows the signalling flow for Call forwarding unconditional being handled by a gatekeeper. My concern is that the figure shows the gatekeeper informing the 'called' user that the call has been diverted away from it, using an H.225 Setup message. In order for this not to create confusion, the gatekeeper must know that the called user understands H450.2 (e.g. if the called user were a Version 1 endpoint then it would surely wrongly interpret this Setup as an incoming call).
The text in the standard which relates to the sending of this information to the called user (H450.2 APDU divertingLegInformation4), states that this message is sent by the gatekeeper only if the option 'served user notification' applies. As far as I can see, this option is a local configuration matter at the served endpoint. My question is, how does a gatekeeper work out whether or not this option is set in a standard way?
