You read my post in VOIP Voice codeing option. The SLC40 was not modem frendly because it used G.726 coding. They were all replaced in the eightys. They were never used for SWITCH to SWITCH transmision. There are carrer problems that can cause modems not to work between switchs but I don't have time now to explain. She Who must be obeyed throws a fit if she can't serf the next. Here is a hint, B8ZS or AMI.
