Does anyone know if anyone provides an interface to allow call control of an Avaya IP462sw telephone via the phone itself? I know it's possible because IP-Agent/IP-Softphone allows this, but is that a proprietary interface? I am looking for SDK or TAPI driver that I could use to develope my own application to control the phone without using 3rd party middle-ware, or Avaya Ct etc..
Any thoughts?
