Whenever I run asterisk, I keep receiving “no matching peer” warning.
[Dec 12 14:47:03] NOTICE: chan_sip.c:21645 handle_request_register: Registration from ‘“XXX XXXX” sip:firstname.lastname@example.org’ failed for ‘188.8.131.52’ - No matching peer found
I used the extensionbefore. However, it’s been deleted from sip.conf. I don’t understand why I keep seeing it. It’s kind of annoying.
Could you suggest me where to look into this issue?
