The inactive status is an indication that there is an active bench warrant outstanding. It is suggested that you immediately retain a local criminal defense attorney. The attorney will contact your probation officer to set up a turn in and attempt to have the warrant lifted.
Mr. Keller is exactly right; the "inactive" designation for status means there is an outstanding warrant for a violation. You've mentioned that it was issued 7 months ago, but do not tell us where the defendant is now. If he is in jail on that warrant he will remain in custody for at least the time needed to resolve the alleged violation(s). he could get time exceeding the time spent in custody awaiting disposition of the violation. If he is not in jail, then the warrant will continue to remain outstanding until he is in custody. Having qualified local counsel would be the way to mitigate the negative consequences.
Inactive indicates the warrant is outstanding, however the case is placed on inactive status until you are either arrested or yourself in
This answer is generally how a lawyer would go about handling a termination of probation hearing. It is not a guarantee that a Court will terminate your probation and does not create a attorney/client relationship between us.
