Hey guys, We currently have 15 Cisco 7940 phones running in SIP mode. All of the phones can initiate a 729 call and asterisk just does a pass thru. We have no 729 licenses on the * machine. We found out that we can't access voicemail because there is no gsm->729 converter. (duh, no licenses). So, we are getting ready to buy some. But, not everybody checks VM at the same time. So we only want to buy 2 licenses. My question is, lets say 2 people are on VM using the 2 licenses. Will asterisk fail over to g711? If it wont, why not? Is there a way to make it fail over? I don't think * will fail over because if I set my cisco phone to "prefered codec = none" and make a call, it goes 729. But if I call VM * says no can do. Why won't * say "no can do, let me try the next one"? sip.conf --------- allow = g729 allow = ulaw allow = alaw allow = gsm thanks, matthew
