Jeff- Thanks for the input. As it turns out, the switch was set to 5ESS Standard. Switch tech changed the trunk group to 5ESSCustom, and all works as expected. I can now busy out channels and call will not land on them until restored to service. -- Scot

Thus spake Scot Desort
Thanks for the specifics, Lon.
What was happening is that if a call hit a channel that was soft busied, the call wasn't rolling over to the next channel. The telco switch was either presenting a reorder tone to the end user, or an intercept stating "Your call cannot be completed as dialed" -- NOT a good thing. The reorder isn't too bad, but the intercept was ugly. If the user re-dialed and landed on a channel that was not soft-busied, the call would go through.
What is distressing is that the DSP did not communicate correctly with the switch. The call should have never landed on that channel - it should have rolled to the next channel in the rotary. If there were no other available non-busied channels, user should get regular busy signal.
Any thoughts as to why this would not work properly? Switch is a 5ESS through a CLEC.
Sounds like an NI-2 translation. Due to the lack of service messages in NI-2, there is no way for the chassis to indicate to the switch that the channels are busied out. So the switch still sends calls down those channels and the chassis responds with whatever cause code is defined (by default 58, bearer capability not presently available). If you switch the cause code to 17, that's a user busy which should result in a normal busy signal to the user...that's a bit better anyway. You real solution is to switch to custom 5ESS translation so you can use service messages and then things will work as you want (soft-busy...calls hunt past). -- Jeff McAdams Email: jeffm@iglou.com Head Network Administrator Voice: (502) 966-3848 IgLou Internet Services (800) 436-4456
