Has anyone ever had this problem before?
The system is an opt 11 with 4 tmdi pris. everything is working fine for over a year up until a couple of days ago when the customer started to complain that -
When they make an ougoing call to an automated service, the service cannot recognize their dtmf tones. for example, when they are told to press 1 to reach customer service - the customer presses 1 but the other end does not "see" it. i've cold started the opt 11, pulled out/rolled the cards, but still to no avail. checked for errors on the pri, everything is clean. just for fun, i installed a universal trk card and then hooked up a fax line to it, it works!
I've also tried calling a live person on the other end. I hear the tones when he presses his keypad, on the otherhand, he can't hear mine. is something blocking it?
Telco already did an intrusive test (whatever that is?!) came back and said pris are ok.
Any ideas? i'm stumped!
