Hi Emam,

This can have multiple issues. It could be network issues, or something in 3CX or the phone itself. Did you already check you Activity log to see what happens to the call? Make sure your log settings are set to medium at minimal.

This could be UDP timeout, SIP ALG, dying phone, bad network routing, unstable network, even the cable sometimes.

As above, check the logs and a capture while making test calls to see what is being sent back and forth.
