Wrong call interconnection in mobile network

Hi Experts.

I think all of us may have observed wrong call interconnection in mobile network.
What could be reason for such interconnections?
Whether it happens at radio link or core?

It is called cross talk, usually the cabling puncturing should be checked on the DDF for TDM tech.

Thanks. So it should not be observed with IP media?

Usually yes, I didn’t work in CN since 10 years.
Maybe there is another issue causing that, I am not sure.

Try to check the MALT device in CN and faulty conference HW devices sometimes.
