Problem: A company had a PBX and used a cell phone for after-hours calls. They called in one day because the cell phone was not working properly, and the cell phone carrier was unable to fix all of its problems. When I inquired why they had the cell phone, they stated it was only for forwarding the calls to other cell phones.
Solution: After a short conversation, I reprogrammed the PBX so they could forward the after-hours calls to various employees and update it as needed. I then walked them through updating the number. They were able to cancel the service on the extra cell phone, saving money for the company.
