We are trying to used a specific pool of number (extension) for the "subscriber-create-on-demand” configuration in osmo-nitb.

Unfortunately, when we used the range from 9570000000 to 9579999999, it returns a different value upon running “show running-config”.

So we tried to change it from the config file of openbsc.conf. After restarting the osmo-nitb application, different value still shows upon running “show running-config”.

But the supported Min and Max value for the "subscriber-create-on-demand random” is from 1-9999999999.

Attached is the config file we used and below is the “show running-config” value of "subscriber-create-on-demand random" value.
