Ok is that for sipgate basic or business one? I have use sipgate.co.uk when I was using chan_sip before and it’s work perfectly but I have change to pjsip using the same setting that other people provide me seemly it’s work occasionally but I definitely will try your solution. So sipgate have change the setting if you telling me to do that.
I don’t know anything about SipGate Business. Sorry. But you have to try Basic PJ_SIP Trunk setting. (Just Disable exist SIP Trunk and add a new with PJSIP you don’t need to delete )
if not works i think you can connect with them, they have some ready wiki pages settings for Asterisk and FreePBX.
You should completely remove them, e.g. paint over the full height of the text box with black or white. As long as you know the fonts involved, it should be relatively easy to recover the text that is even quite heavily blurred. Numbers are even easier to recover.
