I don't think it is even that simple to get rid of. GS trunks would take care of the remote connect issues, but the same issue is still going to exist on the loopstart loops to the phones themselves. if you dial a local extension the other person can still pickup before the first ring if you are using analog phones. All this does is move the problem with analog trunks into a local only situation, but it still exists. > > John Novack > > > _______________________________________________ > Asterisk-Users mailing list > Asterisk-Users@lists.digium.com > http://lists.digium.com/mailman/listinfo/asterisk-users > To UNSUBSCRIBE or update options visit: > http://lists.digium.com/mailman/listinfo/asterisk-users > > !DSPAM:4277dc0474196392812593! > > Jon Pounder _/_/_/ _/ _/ _/ _/_/_/ _/ _/ _/_/_/_/ _/ _/_/ _/ _/ _/ _/_/ _/ _/_/ _/ _/ _/_/ _/ _/ _/ _/_/ _/ _/_/_/ _/ _/ _/_/_/_/ _/_/_/ _/ _/ _/_/_/_/ Inline Internet Systems Inc.
