EC500 on Android - Custom Emergency Number

[tcantintn]

In my country, we have serveral emergency numbers with 3 or 4 digits.

For mobile, the main emergency number used is 112 configured like this:

<!-- Emergency Number can be one of these values: 911, 112, 999 or 08. EMERGENCY_NUMBER -->
<EmergencyNumbers>112</EmergencyNumbers>

It works.

Regarding the others local numbers, I configured the custom emergency numbers:

<!-- Custom Emergency Number -->
<CustomEmergencyNumber>117,118,143,144,145,147,141 4,1415</CustomEmergencyNumber>

The numbers with 4 digits are working.
The numbers with 3 digits are not working. We need to dial 0 before the number.

Somebody could tell me what is wrong?
