I have Hunt Group setup to send calls to another hunt group when the first hunt group is not in service. The fallback hunt group has one member. That user has a forward unconditional setup to send calls to his cell phone. When a caller dials the 888.xxx.xxxx number and chooses 1 for the main hunt group, the caller gets a ring no answer. However, when a caller calls the main number and chooses 1 for the main hunt group, the calls routes to the second hunt group which then gets forwarded to the hunt goup member's cell phone.
