VSA id's higer than 255

We are using freeradius 1.0.4 and having a problem with VSA id's higher than 255 (more than 8 bit). ATTRIBUTE Ascend-Http-Redirect-URL 287 string Lucent ATTRIBUTE Ascend-Http-Redirect-Port 288 integer Lucent When one of the attributes above are sent back to the NAS, it seems that radius is sending it as 8 bit thus interpreted as something else on the Lucent NAS. Any simple solution for that ? Best Regards / Fawaz
