I know that prior to release of firmware 1_4_0_0 for Digium phones there use to be a hard limit of 40 built into the firmware for presence and device subscriptions. I have been running firmware 2_9_10 on Digium D60 phones for the last year and all was fine running subscriptions up to 100. I now have additional subscriptions which takes me up to 161 subscriptions, but for some reason I can only see subscriptions for 151 in my contacts. Setting contacts_max_subscriptions=200 does not help, each time the subscriptions stop at 151. I have even tried a high number such as 900.
Is there still a limit hard coded into the firmware?
If I reduce the subscriptions down to 150 the ones which do not show a status will show correctly so I know its not an issue with the blf, contacts, subscribe set-up.
I am struggling to understand what it is causing the limit to stop.
