My employer recently purchased a private company that uses a Cisco phone system. I am trying to support this system, but I have no experience with VOIP. In previous post concerning one way audio the primary issue seemed to be with routing. This may be my problem as well.
I am using IP communicator to connect to the call manager from our home campus and everything works fine until I try to make a call that uses the PSTN lines. However, users at the remote campus can dial out with no problems.
I set up a second laptop with IP communicator on the same switch as me and I can dial it with no problems. This leads me to believe something on the connection between our campuses is blocking the audio, but I can successfully dial users at the remote campus. I just can't dial from this campus to an outside number.
Can anyone tell me where I should begin looking?
