Troubleshooting phone problems
Troubleshooting SIP phone problems
Pressing a Call Appearance button to answer a call on a 5-series Aastra SIP phone
may not route audio to the phone’s speaker.
This problem occurs if the new call is received when another call is on hold and the handset is
on hook.
Solution:
Use the handset to listen to the call.
The time is displayed incorrectly on a SIP phone.
Symptom:
Wave uses its own time server that you specify during the installation process (as
described in “Configuring the time service used by Wave ISM” on page 7-20), and disables the
Win32Time service. SIP phones may display the incorrect time because the Win32Time service
has been inadvertently re-enabled, and is interfering with Wave’s time server.
