When there is an active call, if another call comes in, the exisiting call suffers, crackly and broken voice.
Site configured with it's CUCM location set to to 120kbps for audio. From what I understand, this controls call in both directions.
I believe incoming calls come come over their WAN link from their main site.
In terms of how busy this site is, I don't believe they have more than 3 calls on the go.
How do I see how many inbound calls are up?
What could be causing existing calls to suffer when new calls come in?
