Sheper,
Sorry for delay getting back to you. I find Rage's suggestion above a good one and you should try it just to see. If the hook flash transfer would work it would be your best solution. Pity you didn't get a call pilot instead of a flash... you would have better options.
I have failed utterly in my attempts to get the Routing service in CICS Rls 6.0 to accept any host signalling options other than pause F78. What this means ... if I am correct in my failure here... is that until Nortel modifies the routing features the route, pool A, B, or C is selected first before any digits dialed. This means that a 'hook flash' can't be conducted on the incomming trunk as the system picks the other line before digits dialed.
Here is a work around that you may find useful - is good only for small office like yours.
Program Flash to answer after three/four rings.. goes to CCR, CCR provides digit selectable contact options for each office member. For those with cell phone, the digit selected takes caller to a Menu. Menu then could give option to leave MSG press 1 or to contact directly, press two.
Pressing 1 would be a lv msg point - goes straight to the voice mail box. Pressing 2 would be an external transfer with the following dial string:
#71P9Pxxx xxxx#89
Your outdial pool is still A, but the flash is reputed not to care. I haven't set this up as I have no flash at this time ... will have one tomorrow, but there is a post that indicates this works from CCR.
Hope this solution works for you. On the other hand I hope others reading this post have some suggestions that would prove me wrong.
Good Luck
PhM
