<p>Based on the info you provided (though wireshark analysis will tell more about it), I am sure what is happening is that rtp coming back from the called doesn't know which ip to go to, because asterisk knows two ip addressses for the same extension due to the way you dialed it, i.e. in ringgroup fashion</p>
<p>I have had this problem once and I never tried registering same extension from two different places after that.</p>
<p>Try Phillip's suggestion, maybe it'll work for you.</p>
