I have a phone that displays the error message "error pass limit". When I research this I found two causes, having an incorrect busy trigger or too many unassinged DN. We deleted all unassiged DNs and have made sure that max number of calls and max busy trigger are set to 4 and 2.
Wondering how to figure out the maximum number of DNs allowed in the system.
Firmware being used is 9-2-1.
If anyone has any ideas please let me know.
Thanks,
Ayaz
I have configured extension mobility for 300 users and i have added 7945 phones with phone templat of 7945 in call manager.
ON 7945 phones when i lift the receiver and when try to dial i get the error pass limit on the screen and no dial tone, when i hang up the reciver it keep displaying on screen forward to.
BUT user are able to login with their user id and password and they are able to make calls, and also they can logout perfect but only i worried abt when the phone is idle without login it shows me the above errors.
I have seen many post saying increasing the max call and busy trigger but in my situation it wont work becz i have confgured extension mobility where each and every phone is without the line.
We have a problem in some Cisco IP Phones 7936, the DN has dissapeared and the phone show the error: Error Pass Limit.
I have found the next, but it is not possible to change Maximum Number of Calls and Busy Trigger parameteres:
