Good day all.
I would like to understand the selection of Carrier Choices in program 10-29-14 : SIP Server Information Setup - SIP Carrier Choice (Carrier A)
How do you know which one to select and what are their impact?

Choice B usually works, why I have no clue, good luck finding answers
trying to understand SL2100 programming is a challenge, NEC never bothered to provide training material and technical information to general public. Only guys who went through SV series training have knowledge. Certification programs never existed for SL series unlike previous DSX
It seems like NEC had plans to abandon on premises systems for years
 
This is for SV8100, but I think the information is also appropriate for SL2100.

Trial & error. Different carriers have different settings. On our Clearfly accounts I found we had no outgoing CID and tried different ones and found it had to be Carrier C.
