first i install asterisk, then follow by zaptel...

then is zaptel still work?

You might run into problems doing this, zaptel needs to be installed first for meetme to be built properly in Asterisk.

If you have installed asterisk before zaptel bymistake then just go to asterisk sources directory and give it a 'make install' again .. it should detect zaptel and compile and install meetme modules properly .
