Is it right to say he did not get my call? In the meaning of he did not answer my call. I tried telling sombody that someone did not answer my call.
He did not answer my call is not equal to He did not get my call.
That's because the former one (didn't answer) comes from the willingness OR some situation where picking up your call was not possible such as the receiver was driving a car.
If you want to say that he did not answer your call, your sentence is absolutely fine.
He did not answer my call and the reason could be anything.
Probably the confusion is the verb get. Get also means understanding. I did not get this information means you could not understand it but here, when it's used for getting a call it would mean there was some problem and the call did not reach to the receiver's phone.
For the medium of electronic communication, get would first mean arrival. We generally ask, Did you get my mail?~ No, I did not. which means we are asking about the arrival of the mail into the receiver's mailbox. To use the verb get for understanding, I'd prefer telling "He did not get what I said in my mail." Because He did not get my mail also means he did not receive it.
We do Internet marketing and often provide a package of sending 'bulk SMSes' through the web. Though receive might be a proper word, we often ask while testing software, "Did you get my SMS"
So, all-in-all, if you want to stay clear, out of these two, he did not answer my call would be a better phrase over the other sentence.
He did not get my call may mean that there was some network issue and the call didn't reach his phone.
He did not receive my call or He did not attend my call are two appropriate ways to say what you wanted to say, while He missed my call will mean he could not answer it for some reasons.
