Ranga It is a pleasure working with you and I really welcome your initiative to build something useful. This was a great exchange on the list today and I am sorry having caught up with it a bit late.
>From the discussion it sounds like the simpler approach would be not to use a >B2BUA and I agree. It was pointed out that it should work both with remote >workers as well as for calls initiated to external numbers (over the PSTN or a >SIP trunk). Both these cases have to work. Once the call is established the >user should be able to do all the things that would be possible with a call >that was directly dialed on the phone. I also agree that it would be a disadvantage to have sipXconfig in the loop for all calls initiated this way. The proposal of offering auto-answer is interesting. How would this work if the user has several phones registered? Could we detect that and only try auto-answer if only one phone is registered? The error handling you mentioned might not be so important as I would assume the user sits next to his / her phone when using this feature. B2BUA: We are interested in a third party call controller in the context of an attendant console. The attendant would be given a Web interface to monitor many extensions in a company. Using 3PCC the attendant could then transfer, or park calls, or put calls on hold. This third party call controller would have to be able to deal with lots of calls and it would also have to be operational in an HA system. I therefore think this is a separate project. Another interesting add-on capability to this click-to-dial feature would be some integration with Outlook or other desktop clients that manage contacts. I have seen examples of Outlook plugins that add a capability to right click on a contact, thereby initiating a call. Hope I didn't cause more confusion --martin
