I currently have 2 IPKs networked via IP using PVA cards. We are using a closed numbering plan for dialing between offices. I am trying to setup a trunk group from remote office to main office to dial out from PRI @ main office. I cannot get PRI @ main office to dial out. It acts like I am accessing the PRI, but I am limited to the number of digits I can dial. If I access PRI and dial 0 I get telco operator. If I access PRI and dial 7 digits I get busy from the IPK.
