Who called from 2136703405

Called cell.  No message.

Call came across my Android mobile phone while I was texting.  Rang once and then ended.  Bo message left.  Likely telemarketing, as the calls have been coming lately.  Call came @ 17:18 on 01.12.15.

Phone rang 4-5 times I didn't answer then they hung up by the time I got to this website...

Last night, I received this number.
Since I do not recognize the number, I did not answer.
No message was left.
