Call Parking Problem

I am having an issue with parked calls. i can park a call with no problem. when i retrieve the call, i can not hear the person on the other end, but they can hear me. any one have any ideas?

fyi, i am running asterisk 1.4.5 with a cisco 7940 and a 7960 phones.


are you picking up the parked call from the same phone that placed it?


Maybe a re-invite issue with these Cisco Phones. Are they running a SIP code ?
