inum forwarded to localphone on sp2--voice is delayed after handset is picked up

Hello,

I have set up an "inum" phone number and I have that forwarded to "localphone" which is set up on the Obi110 sp2. I have google voice on sp1. When people call me at this "localphone" number, the call rings immediately on my phone but when I pick up the handset to answer, I do not hear the party on the other side for about 10 seconds or so. Many times we just hang up thinking there is no one other other side, but come to find out, we have to wait for about 10 seconds to hear the people on the other side. By the way, the party on the other side does not hear us either until about 10 seconds have passed. Is there anything I need to configure for both parties to hear voice as soon as the phone handset is picked up??

Thanks in advance for you help!!
