Is there something out there that will read back the DN of a phone I am calling from? For example... I come across some ratty old analog phone, or a digital phone without a display - have no idea what the DN of it is. Instead of bugging someone all the time to read back the number I'm calling from - is there a "black box" so to speak that'll do it for me? Kinda like when checking POTS lines on a demark, you can dial a carrier's ANAC code (i.e., 1-800-444-4444) that'll read the number back to you.
Also - something that will record something for say 5-10 seconds and play it back in the same call (i.e., testing for 1-way audio issues). Anything out there like that?
Just left field service and now the on-site guy servicing a large facility with some needs. Trying to save time/headaches.
Thanks.
