I'm looking at ADSI phones simply because I don't have to re-tool my entire building; I can use the existing phone network and (I think) get all the functionality I need with the (far) cheaper ADSI phones. My basic ADSI functionality is - (assisted/consultative and blind) transfers - voicemail integration (next/prev/forward, MWI, etc.) - caller ID display - conference - hold/park/pickup - paging - handsfree - DND - global and per-extension speed dial - muting of DTMF A-D from the far-end Now I know that not all of these are currently supported with Asterisk's ADSI subsystem (call park in particular won't show the "extension" you parked the call to on the display), I feel that that is something I can either do myself or pay someone to do. I don't mind paying $300 for professional ADSI scripting software so *'s ADSI parser doesn't mean much to me. The only things I'm really concerned about are the current *insistence* that you use # and *8 and bullshit like that instead of making them programmable or able to put them in the A-D DTMF tones and be able to put them on soft buttons. I am curious as to whether you can do most of these things after a hookflash and how much trouble that will be. For me it's a showstopper that I cannot use * or # in any way I see fit, but I am hoping I can either get a patch accepted to free up those (by way of making the digits required for call pickup and whatnot programmable) or work around it on my own private * system. > You will not get anything near the functionality and feature set of a SIP > phone, and it has the further irritation that much of its signalling is > both in-band and audible. True, but I don't have to retool my office and install POE switches to use ADSI phones, either. No, I will not put a hub/switch at every desk and then use wall-warts for every phone to get around retooling the office. :-) I was also under the impression that * did a pretty fine job of muting the ADSI DTMF tones from the far end. I know my PT350 and 450 phones mute it on their end, anyway. IP phones are nice, I'll give them that... but they are also a pain in the ass if you're upgrading/retrofiting an office, and they also don't play well together -- you're more or less stuck using one brand of POE switch with one brand of IP phone, or you use wall-warts. ADSI phones "feel" much more phone-like to me, even though IP Phones can do some wild things.
