I got an issue with the above mention phone, details follow:
A. Using Phone Firmware 'SCCP41.8-4-3S' - Local & Mobile outgoing call is not working.
B. Using Phone Firmware 'SCCP41.8-4-1S' - Local & Mobile outgoing call work well.
C. The reason being why we utilized 'SCCP41.8-4-3S' is that we got an issue with a softkey button, using firmware 'SCCP41.8-4-3S' address those softkey issue.
1. The Phone Firmware 'SCCP41.8-4-3S' work for a few weeks, suddenly just yesterday '03/10/2009' the local & mobile outgoing call issue occur.
2. CUCM System version: 188.8.131.5209-1
