REGEX Question

Hi,

I have this line:

4311396mS CD: CALL: 2.5.1 State=2 Cut=1 Music=1.0 Aend="Line 2" (1.5) Bend="Tech(19)" [Queue] (11.0) CalledNum=Tech () CallingNum=111111111 () Internal=0 Time=19781 AState=3

It is possible, with REGEX help, to extract data as follows:

Only 111111111 (can be word all sow) where string starts with CallingNum=

I can extract CallingNum=111111111, but I need only numbers :(

Put (brackets) around the 111111111 and use then retrieve the appropriate sub-match.

I haven't got any code at the moment, sorry.

Something like CallingNum=(.*?\s)

???
