Customer ordered a pstn circuit and ended up with a T1 CAS rather than PRI. So naturally the age old how does caller id work.
My understanding is that you need fgd ports to make this work, but I want to be sure of my ground. the carrier is saying they are delivering the number via mdmf format. Isn't that the old delimiter *ani*dnis* kind of thing? My understanding is that ISR routers don't support this. Is that true?
