When you add the hunt group do you add an inbound dial-peer to answer calls to x2000?  Have you enabled debug voice diaper inout and placed a test call?  

 

dial-peer voice 20001 voip

incoming called number ^2000$

codec g711ulaw

dtmf-relay h245-alpha

session protocol sipv2

 

 

Please rate if helpful - Good luck

Can you post the dial-peer to send calls to 2000 across the trunk and the dial-peer to relieve them on the other end?  There appears to be codec negotiation going on.  Have you tried early-offer forced on the outbound dial-peer and setting the codec there as well?  Is the phone you are attempting to ring connected to an analog port on this device?  How do you have the hunt group implemented?
