We've been having an issue at the office with our Cisco CME. Here's the situation.
Phone A (outside line) dials into the main line and after ~three rings the call is huntstopped to four other phones. Phone X answers the incoming call from Phone A and communication can commence, no problems. We will call this the "ORIGINAL CALL"
*Then* Phone B (outside line) dials into the main line and again after ~three rings the call is hunstopped to four other phones. Phone Y tries to answer the incoming call from Phone B but the call is dropped on Phone Y whereas on Phone B the call continues to ring. The phone call from Phone B is actually left in limbo and so long as the ORIGINAL CALL is still in session, the connection to Phone B can never be established and Phone B must terminate their call.
Why is it that when Phone Y or any phone for that matter tries to answer the phone call from Phone B, the call is never connected?
Please see the router config below for reference. I thought perhaps this had something to do with the `huntstop channel` but that is wrong. Maybe this has something to do with the call pickup configuration but I'm not quite sure.

A `debug voip ccapi inout` log has been placed on [pastebin][1].
Furthermore if the call from Phone B is never picked up the call continues to ring and ring on phone B while after about 8 rings on all the 7960 phones the call is huntstopped. If the phone is never answered the call is disconnected (cause code 16) and the call is never forwarded to voicemail for `noan`.
##Another scenario
Take the situation described in the beginning. If phone b is stuck in limbo *still* and phone a terminates the call *phone b* is **still** stuck in limbo. And an attempt to answer that call from phone b when it's huntstopped to the other phones is still fruitless.
