tandem trunking

[coniglio]

i'm in way over my head so please bear with me. We're testing a VoIP solution and my manager has been instructed to have me enable tandem trunking. can't find anything in NTP specifically called TANDEM TRUNKING but did find trunk-to-trunk transfer. is this the same thing? thanks.

not the exact same, when a call comes into your switch, tie or did, a the digits recieved can hit a rlb and send it back out, i use it when i get a network call from a remote switch, the far end is programed to add 9, which hits bars which of course sends it to the network. i also have a route that if i rec 496+ i send add a 9 and send it to my switch in the 496 exchange, their it goes out as a local call, from my tie trunk to the far end cot. if one of my 11's dial a 4 digit exten on another switch that follows a the path from one tie to another tie tandem through my switch.. it's all done in bars and is very simple if you do it one step at a time and document your routes

Well believe it or not I am BARS certified and this doesn't sound easy at all. I'm going to wait until one of my techs has pity on me and calls me to help me out. thanks anyway JohnPoole.
