Nortel CS1000 & OCS

Hi

We are integrating a nortel cs1000 v5.0 with mcm3.0 into ocs 2007

just need to find out a couple of things

we have the following working

1. RCC control - but pbx breakout doesnt work with e164 numbering however if we dial an extension on the cs1000 it works and a 1800 number it works, we get this working by using SPS on the MCM

1. PBX breakout - but rcc now doesnt work! we use SRS on the MCM so we are very confused

Can someone shed light on this? we know OCS 2007 is working and passing traffic right up to MCM when using SPS but then it goes no where the CS1000 doesnt see the traffic unless as i say you dial and extension.

Any idea's would be great..

Thanks
