Thanks Mike this is as well a very helpfull answer, but I asked about hiding the Caller ID. Withheld caller ID doesn’t work even if it is restricted from the originator side which is us. Is there any function in DX2030 tells me this should restrict the caller ID? I’m still not getting in touch with our Termintor to check whith him the ISUP message, may be he ignores the restrict function.
Thanks and regards
