Hi Arvind,

Hope all is well!

Because the Call Forward is ignored on the Hunt Group most people have to take a different approach. An excellent way to deal with this "coverage" scenario is to set up any backup person with the ability to Dynamically join the Hunt Group when necessary. Here is the method;

Dynamic Hunt Group Membership

Hunt groups allow you to set up pools of extension numbers to answer incoming calls. Up to 20 wildcard slots can be entered in the list of hunt group extension numbers to allow dynamic group membership, in which authorized phone users can join a hunt group whenever a vacant wildcard slot is available and they can leave when they like. Each phone user who joins a group occupies one slot. If no slots are available, a user who tries to join a group hears a busy signal.

Allowing dynamic membership in a hunt group is a three-step process:

1. Use the list command in ephone-hunt configuration mode to specify up to 20 wildcard slots in the hunt group.

2. Use the ephone-hunt login command under each directory number that should be allowed to dynamically join and leave hunt groups. Directory numbers are disallowed from joining hunt groups by default, so you have to explicitly allow this behavior for each directory number that you want to be able to log in to hunt groups.

3. Use the fac standard command to enable standard FACs or the fac custom command to define custom FACs. FACs must be enabled so that agents can use them to join and leave hunt groups.

Hope this helps!
