2.1.14 Crosstalk Occurs on Phones Connected to the IAD132E(T)
Symptom
The calls made from outer-office numbers to intra-office numbers can be connected properly.
When you dial a number on an intra-office phone, crosstalk may occur on phones connected
to the IAD132E(T).
Cause
The possible causes are as follows:

The number matches another digitmap.

For outgoing calls made through the FXO port, the peer device failed to collect the
complete called number.
Solution
Step 1 Run the display sip digitmap command to view the digitmap. Check whether the number
dialed matches another digitmap.

If yes, modify the digitmap. For example, if the digitmap is 45xxx|456 and the dialed
number is 4567, the number sent is 456.

If no, go to Step 2.
Step 2 For outgoing calls made through the FXO port, check whether the number dialed matches the
number collected by the peer device. To gradually prolong the sending time, run the sip
soft-parameter send-dtmf-delay-time 350 command.

If no, record on the trunk connected to the FXO port and compare the number sent from
the FXO port with the number collected by the peer device. The FXO port sends the
number too fast for the peer device to collect the number. To gradually prolong the
sending time, run the following command:
terminal(advance-config)#sip soft-parameter send-dtmf-delay-time 350

If yes, go to Step 3.
