Hi Matt,
It would seem that your FXO ports are not clearing down imediatly, I see in the images posted that the release timer and the clearing timers are set way to high, can I propose you lower them down to 3 instead of 10 respectively..
So please look at doing the following (Based on Image #2):
- Go to FXO Port edit
- Click on Timers
- Modify wait release to 3, possibly 2 but your best results will be 3
- Call Disconnect set to 3 and again you can try 2 but no lower as it can have a reverse effect of locking the port up, but 3 is pretty good
- Change the supervisory disconnect to 300ms instead of 350, might not sound like much but that slight reduction can also assist
This is the best place to start, I have no doubt that your lines are not clearing down quickly enough, and I must also point out that this is an inherent problem with analogue lines, in some countries I have noticed that the clear down procedure can take up to 5 seconds and on worst case scenarios can take up too 10 seconds. Here in Australia we also have exchange based timers that can work up to 52 seconds before a line is cleared (But this normally meant for residential customers only, not business lines).
Your TAPS look fine so I do not see that you need to change anything there
Please let us know how this goes, if this does not improve the situation then I would really love some form of remote access to look at this situation, it is familiar territory for me so I have a keen interest in seeing this issue resolved.
(PS) Have you logged a support case for this yet, or were you just waiting to see if the assistance on here would sort the problem out?
Cheers,
David.
