Thank you,
I didn't find it because I was searching in the french documentation, and it wasn't detailled ... In english version, it's OK !
But I'm not very happy to see that CDR format is not as accurate as SMDR format ("hour:minute" only, "tenth of minutes" !!!). This is very bad accuracy !
But in the knowledgebase, I didn't read anywhere that it wasn't possible to install a DeltaServer communicating with more than one IPOffice.
The only thing is : "It is important to note that only a single Delta Server is supported for each IP Office". And in my view, it doesn't mean that a DeltaServer cannot communicate with several IPOffices.
Thanks
