No such command 'sip'

hello
can you help me ?

thank you for your attention

Based on the info provided I think the chan_sip.so module is not loaded or accidently unloaded.

If you type in the cli “show modules” chan_sip.so should be in the list. If not type “load chan_sip.so”

This might solve the problem.

Hope it help, succes
