I have some Linksys Sipura spa2100 units and when calling a station connected to it it rings when answered apporx 2 - 3 seconds then get a fast busy. Can anyone point me in a direction to look at?? My xlite softphone work just fine.
If I read the question right, it could be a codec mis-match. Maybe the allow list for * does not match the ATA list?
Strange thing is that they worked a week ago. I will try and change the codec and see what happens…
