Customer has DSX40 (about 2 years now). He subscribes to "Call transfer" with the phone company whereby he can press [flash], dial a number, hang up, and the call is transferred, freeing up his line. I have the auto attendant set up after hours (dial table 2) for emergency calls... press 1 to be transferred to a cell phone.

Program 4231, Dial table 2, Press 1 = UTRF to #298P
Program 1702, BIN 098 - Line Group 90, and the inputted number is as such: FP7654321P
Software version is now 02.25.... I just upgraded from 01.01 hoping to solve my issue.

My issue is:
This worked great for a long time. About 6 months ago it stopped working. I could program in my cell phone number, and the call would transfer. When I programmed in his number, it would not..... the call would recall to the line and auto attendant. He stated his cell provider takes a long time to set up calls. Now, I cannot get any number programmed with a [Flash] in a speed dial bin to work.

This works manually while on a call, press the [flash] button, dial the number and hang up... the call is transferred.

I think I recall an issue with an earlier version of software where the "flash" was not recognized in speed dial programming.... I cannot get it to work even with the latest software upgrade.

I put a "digit grabber" across the line, made a test call into the auto attendant, pressed 1 and watched the digit grabber display the correct digits. The only thing I couldn't detect was the flash.

I have this very same set-up at my office on a DSX80. Same programming, same software,... auto attendant press 1 does a call transfer to my cell phone after hours. It work every time.

Could there be a timer somewhere that is recalling the transferred call due to the length of time it takes to set up a cell call? (Transfer Recall?, any trunk timer?)

any thoughts?

I would try an extra pause or 2 at the end of the speed dial number, or in the beginning. you will probably have to play with the pauses though.

No.....the telco does the transfer...but you don't have the release option from the telco now...or it wouldn't return to the AA. Now then the pauses should be before the flash and number. The slow setup by the cell company is an inter-company lag time ( know that sip trunking issue?) so the dialed digits really don't go anywhere so the transfer drops and you are returned to the AA. Sound right?


:shrug:

Update:

Per tech support, I added an additional "pause" behind the speed dial bin number in my dial action table where press 1 = UTRF to #298PP.

This worked !!
