Symptom
Users that use POTS phones connected to the IAD cannot hear the two-stage dialing tone.
CauseNo two-stage dialing function for the office route corresponding to the U1900
Inconsistency between the prefix in the number reported by the IAD and the prefix on the U1900
Early IAD version
Solution
Run the show office selectcode no x command to check whether the two-stage dialing function is enabled for office direction x corresponding to the U1900.
If no, enable the function.
If yes, go to 2.
Check whether the prefix on the U1900 maps the digitmap configured on the IAD.
If no, modify the configuration on the IAD. Assume that the prefix is 99 on the U1900, the 99 digitmap must be added on the IAD. Ensure that the minimum length of outgoing numbers corresponding to the prefix on the U1900 is 0.
If yes, go to 3.
Check whether the IAD version is V300R001C03SPC800 or later.icon-note.gif NOTE:
Only V300R001C03SPC800 and later versions support the two-stage dialing function.
If no, upgrade the IAD version to the latest version. For details, see IAD upgrade guide.
If yes, go to 4.
