I’m using an HT818 for an analog phone which should be super easy. For some reason the device will not register. When I search the logfiles it appears as if it is trying to use the MAC address:
NOTICE chan_sip.c: Failed to authenticate device <sip:MACc074ad0be5e6@220.127.116.11>;tag=788929540 for SUBSCRIBE, code = -1
Has anyone seen this on newer Grandstream ATAs?
