Testing a new system with a single Yealink T41P phone.

Phone: T41P - Firmware: 36.81.0.90
(First thing out of the box, I updated the firmware on the phone, using the instruction manual as a guide.)
IP Address: 10.1.10.202

Asterisk system – Ver: 13.13.1
IncrediblePBX Ver: 12.0.74
IP Address: 10.1.10.4

No firewall separating the phone and the server, both using the same switch with no VLANS configured.

Loaded and updated IncrediblePBX, changed Ext 701 User password to match the list I’m using. Configured phone to match User ID (701) and password. The phone will not register. I tried various settings changes on both the server and the phone, but phone still will not register.

Frustrated and wondering if I had changed too many things between the phone and the server, I wiped out the Asterisk system and reloaded clean. I then reset the phone to factory settings. Finally, I changed password for Ext User 701, as before, and then configured phone as before. It still would not register.

I ran full capture of config and pcap. That is all zipped into one file and attached.

I also opened the pcap file using Wireshark. While filtering for only traffic between the phone and the server, I found several attempts by the phone to register with the server. In the server’s reply for each attempt, there was an error “Header not terminated by empty line (CRLF)” I don't know if that is significant, but warnings and errors in responses like that worry me when systems don't work as anticipated.

Any help that anybody can provide will be very appreciated.

Hi David

I check those file and i find that phone send register packet out, but it will get error 'destination unreachable', so please check network between phone and server.

If the issue still persist, please also export syslog from Asterisk server. Let me know if any update.
