How would you go about having calls transferred to a mailbox be transferred directly to a cellphone? This is an Interchange on an FXII. I set up the transfer to field in the MB to "Exxxxxxx" (xxxxxxx being the cellphone). According to the manual The E tells the interchange that this will be an external call. A trace on a test call shows a hookflash, 9 and the cellphone number, however the call stays on hold and does not ring the cellphone. Any ideas?
