No Matching Peer Found


I just got back to the office and my phone will not register with the Asterisk server anymore.
The error is …

Aug 7 18:05:00 pbx local0.notice asterisk[1719]: NOTICE[1719]: chan_sip.c:16355 in handle_request_register: Registration from ‘No User sip:No%20User@’ failed for ‘’ - No matching peer found

Another phone on the same network registers fine with most of the proper network settings.
I don’t know why it is saying ‘No User’. it should be 512

Here is my peer status

Name/username Host Dyn Nat ACL Port Status
512/512 5060 Unmonitored
000/000 (Unspecified) D 0 Unmonitored
219/219 D 5060 Unmonitored
218/218 (Unspecified) D 0 Unmonitored
217/217 (Unspecified) D 0 Unmonitored
519/519 (Unspecified) D 0 Unmonitored
GBHPersonal/GBHPersonal (Unspecified) D 0 Unmonitored
216/216 D 5060 Unmonitored
200/200 D 5060 Unmonitored

Here is my sip.conf

callerid=“Me” <512>
host= ; This device needs to register
mailbox= 512; ; Subscribe to status of multiple mailboxes

My phone is reading ‘No Service’

Any help would be appreciated

According your log your sip device isn’t sending the user in the REGISTER.


I added the Authentication Name and changed the sip setting host=dynamic and the problem seems to be fixed. I still don’t know why this was happening because my other phone doesn’t require the username to be set on the hardphone. something must have been corrupted.

Thanks for the reply.
