I need help with this case below, if someone can help me I appreciate.
Bob is located in site A and he press ForwardAll to your cellPhone.
Ana is located in site B and make a call to Bob, instead the call goes out for the site A via PSTN to Bob´s Cellphone (because the CfrALL), the call "return" to site B and goes out via PSTN of site B.
Anyone seen this?
UCM version 7.0 and later includes a feature called the Local Route Group. This is what you are looking for as it allows you to state that the call should use an off-net path local the the call originator. This is done by attaching a route group to each device pool that contains the off-net gateways/trunks local to the devices in that device pool.
LRG has a long list of uses. In the context of your question, you can assign a CFA CSS that contains route patterns which specify route lists including the LRG. When a call is forwarded the LRG will choose the route group from the call originator's device pool at the time of the call.
