My customer is in the US and I am in the UK. My customer has asked me to help fill out the order form for the PRI, but coming from the UK I am unsure as to some of the questions being asked. The form is asking what "ISDN Protocol" is required, the options are "National 1", "National 2" & "Custom".
Another question was "DID Configuration" - TrunkPackage: Yes/No.
Can anyone please confirm what these options are and advise on what I should recommend.
ni2/national 2 is pretty standard. depends on CO/sentral office you will terminate in.I installed one last week that had to be 5ess although 4ess works in call manager. i would think they are asking you if these are going to be used in A DID scenerio and would need to know how many digits to send..
Sorry for delay, was out yest. Here in Boston where i am, my experience has found if its a long distance service alot of the CO'S are not ni2 compatable and require 5/4ess, with our local service with did's, we are ni2, i would config as ni2 and if theres problems with d-chan coming up, you can try the 5ess config.
