I'm sure this topic has been discussed to death, but I haven't found a comprehensive answer yet... I have a very large installation of Cisco Call Managers connecting directly local and LD T1's for service. I would like to replace some of my LD T1's with IP trunks (or something like that). I would need low-cost domestic and international LD... but quality and reliability is our top priority, so we're not simply looking for low-bid. I assume IAX2 is the protocol I should use, but who are the major players in providing this type of service?
