I recommend you go on a quest for a Telrad guru. There may be some arcane Telrad secrets that will make your life much easier. For example when interfacing with Nortel PBX's you can create DISA trunks which give you internal 'intercom' at which point you can invoke Nortel features & commands including raising the message waiting indicator. Nortel also made (& perhaps Telrad did too) a special ATA intended for interfacing specifically with external voicemail systems. Nortel called it the VMI adapter (NT8B89DA). The nice thing about the VMI was that it handled all of the secret proprietary Nortel signaling voodoo, freeing you from the need to kludge-up a bunch of DISA trunks & routines :-). Just to add 2ยข to what others have said, I think what you're talking doing is a great idea. In my opinion, forklift upgrades concentrate disruption into a narrow window for everyone all at once which can have greater impact than a series of smaller 'fires' that necessarily accompany any migration. That is to say nothing of the non-trivial burden of migrating physically from cat3 2-wire infrastructure to Category 5 MANAGED 802.11af Ethernet. -Karl _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
