Hi All, I was surprised to be told by a Digium support person today that Digium's FXO interfaces (X100P, TDM400P FXO modules) don't support groundstart signalling. This surprises me because as far as I know in a typical PBX configuration with analog trunk lines, groundstart signalling is the only way to prevent Glare.
I just purchased two TDM400P's for a system I'm building to replace our office PBX (Altigen). Since there are no statements anywhere on Digium's website about lack of groundstart support (Actually, to the contrary they boast about all the signalling support in their sales slick), I now need to decide if I want to return the products and switch to a T1 / channel bank configuration. I remember when we setup our current Altigen PBX, we had problems with glare and disconnect detection and so I went through the process of figuring out what was going on and learning about groundstart. After we switched to groundstart everything worked great. In a high use system, it's highly likely that a trunk will experience glare, which is annoying for incoming callers and system users. I'm just a bit baffled as to why Digium wouldn't support groundstart on cards designed to be PBX trunk lines. Someone please tell me I'm missing something.
