ISE 3.1 remove country code for SMS provider

DavidAceti — Mon, 23 May 2022 14:07:26 GMT

Hi all,

I´m integrating the SMS in a guest portal in ISE 3.1 and my SMS provider doesn´t admit country code in the value sent by ISE.

In my case the variable sent by ISE is $mobilenumber$ and the value is +34 XXXXXXXXX but my provider only accept XXXXXXXXX.

My first option was to talk with provider without lucky so now I´m trying to modify this variable on-the-fly ,

if anyone has another idea or how to modify this variable, I would appreciate.

Thanks

David

The ISE SMS Gateway configuration has an option to configure the mobile number sent to the provider:

You will want to customize that JavaScript function to remove the "+34" from the mobile number sent to your SMS provider. You may try something like this:

function mobileNumber (mobileNumber) {
    number = mobileNumber.trim();
    if (number.startsWith("+34")) {
        // remove +34 and remove all non-digit characters
        number = number.substr(3, number.length).replace(/\D/g, '');
    }
    return number;
}

Thanks Thomas,

that was I´m looking for.

I just shortened the javascript function to avoid complain of ISE, and that how I set it:

function mobileNumber(mobileNumber) {

   mobile=mobileNumber.substring(3);

 return mobile;

}

This seems to be a known issue and the work around mentioned above did not work in 3.1.0.518-Patch5. However, It is fixed in 3.1.0.518-Patch7.

https://bst.cloudapps.cisco.com/bugsearch/bug/CSCwe70975

Symptom:

once we tried to configure

function mobileNumber(mobileNumber) {

return mobileNumber.replace("+1","");

}

to remove +1 we see into pcap that +1 it is still sendin it even if the javascript is executed

Conditions: in ISE 3.1 patch 5 Workaround: no available Further Problem Description: this seems to be a regression of defect CSCvz66577
