There are a few reasons why you would see the status as EM_PARK. Typically if you would be running into an issue with the DSP's where they wont respond to the DSP manager, you would see the ports go into EM_PARK. Solution : Upgrade to a code greater than 12.2.6 to prevent the DSP's from timing out and staying in hung state. The other issue could be that after a call is released, the PBX would continue to sieze that channel and not do the release, and the router would eventually put the state of that port into EM_PARK. Solution : Fix the PBX so it releases the channel, or bounce the T1.
