MGCP can make it work only if it's going to be hairpinned via the PSTN. If you use H323, you can run it in and out on VOIP dial-peers.
H323 would likely be a better way to go if you must do this. That said, this is a pretty strange requirement. I would ask some hard questions about exactly WHY this needs to be done. It might be more appropriate to do something where you are working with CDR after the fact and billing based on that back to the originating station. ----- Original Message ----- From: "Mann Chaddha" <mann.chad...@gmail.com> To: <ccie_voice@onlinestudylist.com> Sent: Tuesday, March 31, 2009 12:55 PM Subject: [OSL | CCIE_Voice] FAC on Internal DN Hi We’ve come across a typical requirement wherein we need to enable FAC(Forced Auth Code) on an Internal DN. I was thinking of creating a RP & hair pinning it back from a GW to the required DN.This DN could be only in this GW's CSS. Is this possible with MGCP or I need to have only H.323 GW? What will be the required config on the Gateway? Thanks Mann
