[Asterisk-Users] doubling digits

[Omar Abhari]

But see, we are not an "IVR calling card" company. It's a prepaid 
wireless gig. There is no transferring or what not. It's all simple DB 
transactions. All the cellphones that customers call from are digital 
TDMA phones, very good quality, mostly new. Land line, or cell phone, 
the problem still persists.
