<div dir="ltr"><div>Hi there</div><div><br></div><div>That answer includes using tcpdump to check for SIP packets and examine the register packet. At this point you have no SIP packets coming from your phone so you are not upto that stage yet.</div><div><br></div><div>You need to know why there are no SIP packets coming. My guess is your config files have a typo in them. You can modify the ones I sent to see if they work for you. You do need to validate your configs. I recommend telnet to the phone, and checking the display settings to see if it has picked up the settings. Equally check the phone logs. It will tell you which files have errors.<br></div><div><br></div><div>Until you get the settings loaded correctly nothing else will matter<br></div><div><br></div><div>Enjoy your break. If you want to use Voip you should definitely spend some time to learn tcpdump. If you want to use Cisco you need to be able to understand the configs yourself and get as much info from the phone as possible. Not hard but it takes a little bit of time.<br></div><div><br></div><div>Cheers Duncan<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Dec 22, 2020 at 10:43 PM Turritopsis Dohrnii Teo En Ming <<a href="mailto:ceo@teo-en-ming.com">ceo@teo-en-ming.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Good day from Singapore,<br>

I seem to have found the solution at FreePBX community forums. Please <br>
check out the following discussion thread.<br>
<br>
Discussion Thread: Cisco 7940 registration problem RESOLVED<br>
Link: <br>
<a href="https://community.freepbx.org/t/cisco-7940-registration-problem-resolved/30285" rel="noreferrer" target="_blank">https://community.freepbx.org/t/cisco-7940-registration-problem-resolved/30285</a><br>
<br>
But I don't understand very well what users at this discussion thread <br>
are talking about. Can someone help me understand better after reading <br>
through the above discussion thread?<br>
<br>
For your information, I am using PJSIP extension instead of CHAN_SIP <br>
extension.<br>
<br>
I am planning to work on my Cisco 7960 IP phone registration problem <br>
this coming Christmas 2020 weekends.<br>
<br>
Thank you very much for your kind assistance.<br>
<br>
