You have to clarify one thing: _What_ are you actually paying for ? a) established B-Channels b) SETUPs routet by the Telco to the destination In Germany, a) is used and allows a callback without any units counted for the initial caller. I don't know who uses b) [hearsay: Austria does?]. Obviously b) is close to train robbery - you pay per call, even if the callee is busy or has no device connected. In this case you cannot avoid paying the call expect going shoot the telcos CEO. If you are in a relaxed situation (a) you just have to: 1) Set "Expect Callback" at the caller side 2) Set "Callback" at the callee This gives you callback, but eventually still PPP one. To get it bill free: 3) Enable ID Auth on the callee (at least prefer) 4) Set the "Calling #" Now the callee can decide whether a call is from a caller to which call- back is to be used, refuses the call (you don't pay) and finally calls back itself. In practice you may have other problems with callback timing and call collisisons. If that happens, travel this lists archives for the solution. -- Kanther-Line: PGP SSH IDEA MD5 GOST RIPE-MD160 3DES RSA FEAL32 RC4 +-o-+--------------------------------------------------------+-o-+ | o | \\\- Brain Inside -/// | o | | o | ^^^^^^^^^^^^^^ | o | | o | Andre' Beck (ABPSoft) beck@ibh-dd.de XLink PoP Dresden | o | +-o-+--------------------------------------------------------+-o-+ ++ Ascend Users Mailing List ++ To unsubscribe: send unsubscribe to ascend-users-request@bungi.com To get FAQ'd: <<A HREF="http://www.nealis.net/ascend/faq">http://www.nealis.net/ascend/faq</A>> </PRE> <!--X-MsgBody-End--> <!--X-Follow-Ups--> <!--X-Follow-Ups-End--> <!--X-References--> <HR> <STRONG>References</STRONG>: <UL> <LI><STRONG><A HREF="msg09741.html">(ASCEND) Nynex (BA) PRI Callback</A></STRONG></LI> <UL> <LI><EM>From</EM>: "Matthew S.
