Capturing traces and logs 225
Symptom:
The telephone is on Call Forward to another number. When the Office
Communicator user who is associated to this telephone logs in (this
telephone is controlled by the Office Communicator user through SIP CTI),
the Office Communicator cancels the Call Forward.
Possible cause:
This is a Microsoft issue that Nortel has escalated to Microsoft.
Solution:
No solution yet.
Office Communicator disconnecting from the network
Problem:
Office Communicator user cannot control the telephone after having been
disconnected several times.
Symptom:
Customers using smart telephones or Mobile Communicators cannot take
control of the telephone after having been disconnected abruptly three or
more times. This disconnection could be due to your network (for example,
GPRS or WLAN).
Possible cause:
This problem occurs because the SIP CTI link is disconnected abnormally
and the Association is out of service for 30 minutes (1800 seconds). This
timer is hard-coded by Office Communicator and cannot be changed.
Solution:
Increase the Maximum Associations per DN on the Signaling Server
through Element Manager. This field is configured to 3 by default. Increase
this parameter to allow more network disconnections.
