You English is very poor, so I am only assuming what you are doing is
connecting two machines each with an E1 card and one running Asterisk,
perhaps the other a phone system.

The problem is both ends think they are pri_cpe. See this for information on
how to configure your Asterisk and zaptel correctly:
