We just installed a new system spanning CenturyTel & SBC LECs. The problem we are having on our CenturyTel (Seimans CO)PRI is we can't get our new SBC(DMS CO) prefixes to go out over it. CenturyTel states that the PRI is programmed correctly, but that the subparty calling line information needs to be "Allowed". The person that stated this is a Seimans expert, so he said he's not sure where this would be changed on a Meridian PBX. Anyone know what he may be talking about???
