Hi all, Would anyone be able to point me in the right direction as far as the pros/cons of using a local loopback with a T1 provider, or just peering with a company using SIP/IAX2 or my small office asterisk setup? I've seen setups in both scenarios. The only potential pro of the T1 that I can think of is quality of voice and having an SLA with a provider. Otherwise, are the costs justified? Thanks for your input. /sf
