Monolog
8.5.1 Fault
Monolog occurs when the IAD and OPENEYE directly call each
other. The voice from the IAD side cannot be heard on the OPENEYE
(SIP-based). After various models of IAD, including 101, 102 and 108,
are tried, the problem remains. However, communication between
IADs is normal, both IAD and OPENEYE are successfully registered,
and their interaction with the softswtich is normal.
8.5.2 Cause
Since the IAD communicate with other IADs normally, IAD
hardware faults can be ruled out. You can consider replacing the PC of
the OPENEYE.
8.5.3 Processing Procedure
According the fault phenomena and causes analyzed above, the
processing procedures are as follows.
1) After installing the OPENEYE in another PC, communication
returns to normal.
2) Check the faulty PC. It is installed with two network cards.
One network card (hereinafter referred to as card 1) is
integrated on the mainboard; the microphone and
headphone interface are also integrated on the mainboard.
Another network card (hereinafter referred to as card 2) is
plugged in the extended slot of the mainboard.
The IP addresses are planned as listed in Table 8-6.
