Yes, I am repeating a question I have seen on other netpro threads. No, I am not a complete idiot. Though, the question may be considered a lean to idiocy but I'll ask anyway.
So, I see that other folks have posed the question on whether one should pick ground-start, loop-start, or POTS when adding a port to a VG-224 gateway that is configured as a MGCP device in Cisco Unified Communications Manager (CUCM). In a couple of those threads I have seen people say "always use POTS" or the incredibly information one words response: "POTS". But I have not seen an explanation as to why POTS versus say loop-start?
I understand the difference between loop-start and ground-start. What I don't get is why POTS is listed as an alternative to either one of the aforementioned options. Meaning, I have seen plenty of documentation that explains loop-start as the signaling method normally used by POTS lines. I never thought of them as mutually exclusive. Can someone help me with what I am missing here? Clearly there is some difference as the config options for loopstart are different than POTS.
It it helps, I am using the VG-224 for basic analog stations, fax machines (mostly), and modems (POS systems). I am using MGCP because I need CA-controlled T.38 fax relay.
Thanks in advance.
