CUCM/Unity Connection - Tranferring a call to multiple cell phone numbers

When someone calls my main office number, the opening greeting is played, and their is an option that says "For Technical Support, Press 2". If the caller presses 2, during our open hours, this call will then be transferred to the help desk ringing all phones in that department. During closed hours and weekends for technical support, I have a call handler configured with a caller system transfer, that transfers technical support calls to a call center (This is a regular PSTN #). We are getting rid of the call center, and I need to figure out how I am going to handle after hours and weekend calls. I was going to modify the caller system transfer to just call the cell phone number of the person on call, but if that person doesn't answer for some reason, then I have an unhappy customer. Is there a way to configure the caller system transfer so I can get it to ring multiple cell phones. Like put the cell phones in some sort of hunt group of something? If not, do you know of any other solutions that may give me the desired outcome I am looking for.

I have never used the product but  CUCCX sounds to be one solution.
The below is a link to an older version of the software, it allows you to write scripts for CUCM.
