I have a vg200 running 12.2(13b) h323 gateway services through a t-1 connected to a fujitzu PBX. Every so often the outbound traffic is halted and I receive a fastbusy. The circut will return to normal upon reload of the 200. I have checked the t-1 interface and it shows an up status plus when I do a "sh voice call sum" I'm not seeing any locked channels. I have read about the same type of problem on gateways running mgcp, but this is a 323.
Any help will be well received. I currently have to reload the 200 twice a day.
