Finally I got.
After many testing parameters, I obtained success results with this code:
// Testing (VSA) WISPr
$racct->putVendorAttribute(14122, 2, "Sao Paulo, SP", $type = string);
$racct->putVendorAttribute(14122, 1, "isocc=BRA,cc=55,ac=11,network=LinktelHotSpot,ha=Office", $type = string);
The result log message done:
WISPr-Location-Name = "Sao Paulo, SP"
WISPr-Location-ID = "isocc=BRA,cc=55,ac=11,network=LinktelHotSpot,ha=Office"
