Before we start, you need to answer the most important question: Has your Asterisk server properly authenticated with your voice service provider (VSP) yet?
How can I edit SEPmacaddress.cnf.xml file
You can use any text editor. I like to use Notepad++ so you'll know which XML tags are left "open".
what is important to connect to asterisk.
When you edit this file, search for an XML tag called <loadinfo>. Use the same version as stated there.
Not works. Please, do you able send me config file for this phone to SIP account:
SIP asterisk server: 192.168.106.3
Thank you very much.
What troubleshooting have you done???
What is your settings on your Asterisk server?
Are you using TCP transport or UDP?
What firmware are you using?
Did you enable TFTP so the phone can download the SEPmacaddress.xml.cnf file?
