Grandstream FXS won't register - Trying to use MAC


(Mvogel4949) #1

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[2173] chan_sip.c: Failed to authenticate device <sip:MACc074ad0be5e6@224.0.1.75>;tag=788929540 for SUBSCRIBE, code = -1

Has anyone seen this on newer Grandstream ATAs?

SUBSCRIBE relates to message waiting notifications and has nothing to do with registration.

Try to find a log entry for registration failing.

Good call. There is nothing in the full logfiles regarding wrong password or failed registration. It’s almost as if it isn’t getting to the freepbx
