Hello. 
How can I call a mobile or landline phone with computer using a program
Sipek Softphone? 
I tried different ways, but I do not get. 
For example using the program 3CX everything works, I dial: 00ZYYYXXXXXXX,
but Sipek Softphone is not working.

You need to use a sip -> pstn (or A Z Termination) company to provide the 
connection. This is not some-thing the the sip client does.
