I'm trying to call the "contact_site_page()" found in the "contact" module function from another custom module. Basically, I want to add another path that displays the same form as www.somedomain.com/contact. I am trying to do this with "hook_menu_alter", is that right? It all works except when I assign "contact_site_page" to the "page_callback". Throws a "Call to undefined function" error. I really just want to know exactly how I can call functions from other modules. Can anyone help?

Here is what I have been trying:

<?php 
function myModule_menu_alter(&$callbacks) {
  // Example - disable the page at node/add
  //drupal_set_message('this alter function is being called');
  $callbacks['myNewURL']['title'] = "Next Steps";
  $callbacks['myNewURL']['page callback'] = 'contact_site_page';
  $callbacks['myNewURL']['access arguments'] = array('access site-wide contact form');
  $callbacks['myNewURL']['type'] = MENU_CALLBACK;
}
?>

I would also like to know this. Is it possible just to include the module file?

I think you could use drupal_goto('contacts'); I'm not certain though, I haven't used hook_menu_alter before.

If the module exists, you should be able to just call the function. For example, taxonomy is a module in Drupal. Often I deal with modules that need to work with the taxonomy terms of a node. I usually just assume those functions from taxonomy exist when writing code.

I think the function must also be in the .module file. If it's in a .inc file, it seems not to be callable.

To call a module function defined in a file different from the .module file, you should load first the file using the module_load_include function (version 6.x-7).
After that you can call the function normally.

module_load_include('inc', 'feedburner', 'feedburner.admin');

Can be used to call functions that exist in a file called feedburner.admin.inc in the feedburner module as an example.

That function is in 'contact.pages.inc' which is not included automatically by drupal. You need to add two more keys to the menu:

function myModule_menu_alter(&$callbacks) {
  // Example - disable the page at node/add
  //drupal_set_message('this alter function is being called');
  $callbacks['myNewURL']['title'] = "Next Steps";
  $callbacks['myNewURL']['page callback'] = 'contact_site_page';
  $callbacks['myNewURL']['access arguments'] = array('access site-wide contact form');
  $callbacks['myNewURL']['type'] = MENU_CALLBACK;

  $callbacks['myNewURL']['file path'] = drupal_get_path('module', 'contact');
  $callbacks['myNewURL']['file'] = 'contact.page.inc';

}

The most general answer to your question is: Use module_invoke. module_invoke('node','show',123), for instance, is like calling node_show(123).

For your more specific needs, you could try drupal_get_form. Specifically, try drupal_get_form('contact'). I don't know how this will work if the contact module hasn't been included yet, but you can give it a shot.

I haven't used hook_menu_alter, but based on the Drupal API page for it, it doesn't look like what you need. drupal_goto would work in some cases, as meadtj says, though it will actually redirect the user to yoursite.com/contact.
