Shouldn’t those match?

this is a new install of freepbx this hint configuration is made by the same freepbx how i can resolve this issue?
i migrate from Elastix 2.5 to Freepbx

Not sure. I expect it’s either a setting in your phone or (if you’re using EPM) a setting in the button config.

i try whit the next phone

cisco SPA504G not Luck
Avaya 1120E Sip Firmware not Luck
Fanvil C400 not luck
Fanvil C600 not luck

i performance a manual configuration of the phone

add custom field on Freepbx web gui
subscribecontext = from-internal
