Could you please help me with a such configuration:
I have CME router. I need to configure a such scenario:
Mobile phone -> CME -> forward to external IVR system -> back to the CME -> ip desk phone.
I need to save original calling number of my mobile phone, I want to see it on my ip desk phone.
Now I have such configuration that on my CME I replace mobile calling number with my DDI pool number because operator reject outgoing connections with calling party number (my mobile number) which is not in DDI pool.
