Hi, I have two Asterisk server linked by a IAX2 trunk with two PRI+DID: Site1: XXX<100-499> Site2: YYY<100-499> (I masked real number with XXX and YYY) PSTN PRI1 --- Asterisk1 ...IAX2... Asterisk2 --- PSTN PRI2 Users: - keep their extension when moved between sites - can be reached from PSTN with both XXX<ext> and YYY<ext> In other words, dialplan is shared between servers. Actually, we have two Alcatel PBX 4400 working in this way. Can I do this with Asterisk? Thanks Mimmus
