I have an IP Office 403 with PRI interface. I need to connect this to an Avaya Definity G3Si R8 PBX. Both units sit in the same room side by side. I have a spare T1 circuit pack inside the Definity to use for this project. The only thing I need to do is get dial tone on the IP Office from the Definity. The Definity has 3 PRI's from telco. Can this be accomplished with the items noted? Can the systems be hooked up back to back? I've been told conflicting answers but need to establish if this can be done. I'm looking for someone with real world experience that has done this. Please advise.
Thanks
