Call routing - How can I allow dynamic CLIP routing?

If you want to allow AutoCLIP routing for calls from GSM, go to GSM incoming groups and set following parameters:

1. Time to keep CLIP in table to number of hours during which you want to keep a record in the memory (it has to be higher than 0 in order to activate this feature).
2. Check Add record only for unconnected call in case if you want to use this feature when a called person does not answer a call.
3. Check Delete record for connected answer in case if you want to delete record when a such missed call (mentioned in point 2) is answered and connected to the correct extension.
