Hi there,
I saw on your post and you said you have your SIP credential, I got it to thru the script of Github.
The password are 12 caracters (numbers and letters only) I guess yours are the same.
My plan is to use a Grandstream HT801 or Grandstream HT802 but I’m kinda scare in just throw my money away due configuration troubles.
I read were succesful to use Zoiper for your Telmex modem (ONT), How did you do that? If you can help me please or anyone reading this, I would appreciate so much.
