[Freeswitch-users] missing digit from destination number, overlap dialing

Tue Jan 24 18:54:33 MSK 2012

Dear all,

May I ask you for help?

We use Freeswitch with Sangoma B700 FlexBRI
on Windows XP professional SP3. We have 2 BRI lines.

Some external calls lack the last digit of the destination number.
Many destination numbers are ok.

It depends from the source of the call.
Calls from German mobile network have complete number.
Many calls from German landline have complete number.
A few calls from German landline lack the last digit.
This callers hear "Called number is not available".

Freeswitch received the complete number from 68% of the calling numbers at all times.
This means 7 digits after the country code.
Incomplete number from 14% at all times. Only 6 digits.
18% varied. Sometimes we received 6 digits. Sometimes 7.

I tried  <param name="overlap" value="yes"/>  in the file freetdm.conf.xml.
This makes the external caller do not receive an answer. He hears nothing.

----------------------------------------------------------------------
This is an extraction of the freeswitch.log without overlap=yes:

    Line numbers 02, 04 and 19 lack the last digit.

    Line numbers 01, 03 and 10 from mobile network.
    Line number 13 anonymous caller.
    Other from landline.
