Right, I know that the voice part is POTS because I have a standard cordless phone plugged into our Partner system.
Hmm, wouldn't ETR be covered under a patent and not a copyright? And has 17 years been up yet? And if someone is selling devices that convert to/from ETR, then the protocol spec is available in some form (even if it's some draconian Avaya licensing scheme). I agree that Avaya has a vested interest in keeping the spec out of the public eye (sell phone upgrades, sell Merlin adapter modules), but this technology is definitely getting long in the tooth....which doesn't mean that my users exactly want to give up the familiarity of the Partner phones just yet. ;) And since I already have Partner phones, and don't really care to spend $200-$300 a pop to replace them with Snom or Cisco phones (good as they may be)... My goal is to get rid of that box on my wall. I already got rid of one (Cisco 1720 that was our router, replaced by a Linux server/router), now I have two to go (Lucent ConnectReach for our Time Warner Telecom IBL, and the Partner ACS phone system). Hell, Lucent Technologies ought to pay me rent for the amount of space they occupy on my walls. [rant=on] It is completely obnoxious to me that I have to take an incoming channelized T1 and have it broken out into physical copper wire so that I can insert it into my Partner system for voice. If I had then to take that copper, spend beaucoup more bucks to be able to put it back INTO digital form so that it can work with an Asterisk PBX...that's borderline surreal to me. Everyone is so vested in making sure that none of their damned equipment interoperates with anyone else's (yet all the while paying serious lip service to the holy grail of "standards") that I am to the point where DCMA be damned, if I can measure it I can figure it out. It pisses me off no end that TWTC can't simply send a normal T1 into my business (and therefore allow me to use a simple T100P), and I'll bet that when they start offering VoIP in this area (SW Ohio) it'll also involve some absurd piece of proprietary equipment further to clutter up my wall or rack. [rant=off] At any rate, yes, I could pick up a TDM400 and have Asterisk act like Partner ACS analog extensions, or pick up 3 X100's and use it directly for the incoming lines (and then deal with the user fallout regarding adaptation to X-Lite or something similar), but I just can't bring myself to do it, honestly. Ultimately, I want those boxes off my wall because technologically, they do not need to be there. Guess I'm stuck with finding 7960's on eBay as cheap as I can. *sigh* Anyone want an outmoded Partner ACS R1.0 analog phone system? ;) Greg On Wed, 2004-04-07 at 17:46 -0500, Steven Sokol wrote: > > On Wed, 2004-04-07 at 15:44 -0500, Eric Wieling wrote: > > > Don't expect the fancy function buttons to > > > work, however. > > > > > > > That's specifically what I was asking about... > > > > Has anyone tried to decipher the ETR signaling protocol?
