RE: CTI development

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Jan,
I tried the latest manual. Indeed it is mentioned that release 2.05 
contains a CallTransfer implementation.
However further I don't see any reference.
Or do you mean the external ACD application, which is working on the 
virtual queue notifications?

With CallTransfer I mean the feature that an active call from A->B can be 
changed in a call from A->C or from B->C.
Such behavior is possible with H.450 implementations in someH323 terminals. 
 Indeed those implementations are built around users initiating this by 
pressing buttons on their terminal.   However such behavior can be 
initiated by an application as well.
For instance, as far as I understand, it is not possible with the current 
gnugk to route a call to another destination if the original call isn't 
answered or released because of a busy terminal.
It would be an enrichment of the CTI model if this could be done.

Regards
Dirk

Try the manual: Virtual queues and TransferCall are available in the
regular releases via the status port.

Right now nobody is working on H.450 as far as I know. Most (all ?)
H.450 procedures need support by the endpoint and from what I hear that
is still pretty hard to find.
Some endpoint initiated H.450 procedure work with GnuGk, because the
gatekeeper doesn't have an active role in them. But I don't have an
overview what does and what doesn't.

Regards,
Jan
