Finally upgraded to 220.127.116.11 from 1.0.x which we have been using for years. Now when we transfer a call to a polycom phone (we use 600s) the call rings and is picked up, but the recipient cannot hear the original caller. The original caller CAN hear the recipient! Doesn’t happen when we transfer to a Grandstream phone, yet they are set up identically in extensions.conf.
Does v1.4x require changes to the Polycom setup? Anyone know what they might be?
(BTW: setting the verbosity high reveals nothing remarkable… no errors, successful transfer of the call, etc.)
