I have the same problem, only my customers report that it only happens
occasionally. Most of the time, they can transfer calls just fine.
They can also put calls on hold and retrieve them as expected. However,
sometimes, about once a day, they try to recover a call and the caller
can't hear them, but they can hear the caller.
I've seen this happen once, but I've been unable to reproduce it
reliably.
Any ideas?
