I have a 509G in SIP on asterisk (trixbox). Is it possible to create a button that will blind transfer to an extension? I am basically looking to make a one touch park button. The user would hit it and the phone would initiate a blind transfer to extention 70 (the parking lot). I learned how to modify softkeys in a previous thread but am unsure of how to replicate this particular need.
I have not had any luck. I do not think what you are doing will work. The problem with the speed dial function is the phone by default creates a new phone call. You are essentially parking yourself. What we need is a blind transfer to 70 in one touch.
