Troubleshooting IP Trunks
The tools and techniques used to troubleshoot connectivity problems with
IP Phones also apply to IP trunks. Other problems with IP trunks, such as
poor voice quality and traffic congestion, are often the result of incorrect
CDE programming or insufficient bandwidth.
The following sections summarize the programming requirements and
provide guidance on addressing problems with connectivity and other
quality of service concerns. For more detailed information, see the
SX-200 ICP Technical Documentation, especially the section entitled
“Maintaining Voice Quality of Service.”
CDE Check List
Form 01, System Configuration
Ensure that the IP trunk card is programmed in Bay 1 Slot 6.
Form 03, Class of Service
Ensure that the following options are enabled in COS 7:
-
801 Incoming Trunk Call Rotary
-
802 Limited Wait for Dial Tone
-
811 ANIS/DNIS/Class Trunk
-
702 SMDR Overwrite Buffer
Form 04, System Options/System Timers
Ensure that IP trunk-related options are programmed as follows
-
Option 86, PRI Card: QSIG: Enabled.
-
Option 115, Maximum IP Trunks: 1-16 depending on traffic.
-
Option 120, Compression Resources: Compression is
recommended with IP trunks to conserve bandwidth.
-
Option 132, DSP Configuration Option: Business 1.
Does the DSP Configuration match the hardware installed and
Compression Resources purchased? It may be necessary to
purchase an additional DSP card(s) to satisfy DSP Configuration
and Compression requirements. For more information, see
