Friends, I use asterisk 13 and I have an active client making calls, but when I give a sip show peer ******* this peer appears without any ip information, useragent etc, it looks like it’s offline, has some way to block this user.
sip show peer [peer name]
if the status is UNKNOWN, the device is not register so it is not reachable by Asterisk because Asterisk cannot locate it
Is this client a valid user in the sense that it is listed with “sip show users?”
More detailed info would come from “sip set debug on” for chan_sip, or “sip set logger on” for chan_psjip.
In the simplest case, you could simply remove this user from the configuration.
Make sure allowguest is set to “no”.
Check DEVICESTATE from the dialplan.
