I need to know how to set the TX dial out prefix for a PBX IP phone system. I need to dial 8 on the phone system to make outside calls and need to set the same dial 8 option on the TASKalfa 400 MFP's in the building. I've checked command center, the entire user settings menus, and the service mode fax settings including the modem settings.

It is possible to set a default dial prefix? I've done it on Konica Minolta MFP's (C280's, b451's 751's,) but need a little help with the Kyocera brand.

Thanks,

Brandon
