The story so far is that I've been having problems when using GrandCentral's outbound calling Click2Call feature. The people I'm calling have been complaining that there is a long silence when they answer, leading to their saying, "Hello...hello, etc." and then, occasionally, hanging up.
Since I'm making real work calls with the GC Click2Call service, I stopped using it for most important calls. Yesterday, 31 Jan 08, after one problem in the morning, I used it a couple of times in the afternoon with people likely to be understanding and they reported no problems. So maybe it's a transient problem.
I did have another problem yesterday, which I had forgotten before, when someone called me using my GC number. The GC robot said, "Press 1 to accept," which I did, since it was a coworker, and nothing happened. I pressed "1" several more times, but the my coworker and I never connected. (I called him back and apologized.) This happened again with another person who wasn't so understanding.
I've started telling people to use my GC number and now I'm really hoping I don't have to tell these same people to go back to the old numbers. People don't understand why I list one number for voice and another for SMS anyway (and some people don't know that SMS=text), so the whole thing is confusing for them.
