VoIP command reference 249
Parameter Value Description
inMsg
0
1
0 = disables printing of SSD messages to the TPS
1 = enables printing of SSD messages to the TPS
outMsg
0
1
0 = disables printing of SSD messages from the TPS
card
1 = enables printing of SSD messages from the TPS
card
Note: The enable all TN option (–1) on a busy TPS with caution due
to the number of messages printed for each call. Remember, not only
are call processing messages printed, and all lamp audit messages
are printed.
You can temporarily turn off the lamp audit function from LD 77 (the
password is 9950). Enter dlmp=1 to turn off lamp audit and dlmp=0 to turn
it on. You can also turn on SSD messages at the Call Server side (for
comparison) through LD 77. To turn on the messaging, enter
dmtn <tag
#><TN>. To turn off the messaging, enter kill <tag #>.
Entering only some of the parameters is the same as setting those not
entered to zero, so ssdTrace 0xTN turns off printing in both directions,
while ssdTrace 0xTN,1 turns on printing for incoming messages and turn
off outgoing message printing. A partial entry with "all TN" -1 provides a
quick way to disable all printing: enter "ssdTrace -1".
Comparing the captured SSD trace with the one produced from LD 77 on
the Call Server can identify if any SSD messages are lost. The point of
reference for the direction of the messages is reversed when comparing
the two log files: SSDO on the Call Server trace is SSDI on the ITG trace.
For each message, the following prints:
• task receiving or sending message
•
timestamp when message was processed by the TPS
•
syslog priority of this printout (all are Info messages)
• TN of the IP Phone sending or receiving the message
• direction of message flow relative to ITG (SSDI for incoming messages
from the Call Server, or SSDO for outgoing messages to Call Server)
• a hexadecimal word of the SSD message contents
-> ssdTrace 0x6005,1,1
value = 56170928 = 0x35919b0
