Just saw over this past weekend AMR Buffalo crews running Sonim XP7 or 8's with lapel mics. Still had their HT1250's as well. I heard through the grapevine they were switching to FirstNet and some PTT app for company operations. Voice sounded decent. Does anyone have info on this? I haven't heard any traffic on their LTR Passport TG's on Saia's system tonight however, I heard AMR Dispatch the background while monitoring a local fire dispatch the other night. That was the same night I saw the Sonim phone/radio in use. By the looks of it, they were using ESChat
