JIRA can be setup to store details from phone calls. This is particularly useful when using JIRA in a help desk and support environment.
1. Setting Up A Phone Call Issue Type
You can create a custom issue type with custom fields for call duration, participants, location, phone number etc.
2. Creating New Phone Call Issues
You can use the the normal Create Issue screen for this task. To save time, you may like to shortcut to the 'http://confluence.atlassian.com/display/JIRA/Creating+Issues+via+direct+HTML+links' It may also be convenient to use the Quick Create portlet, though this will need the user to enter custom data by after creating it. A third option is create a customise phone call details form to allow entry of custom field content such as call duration and phone number while adding the issue.
Use JIRA Quick Create Portlet
Simply install the JIRA Toolkit and setup a Quick Create portlet on your JIRA dashboard that adds a phone call issue to the relevant project.
Use Custom Web Form
This involves setting up a Confluence page or site form and using it to send emails to the [JIRA Advanced Mail Handler]. You'll need to customise the [Advanced Mail Handler] source to handle any custom fields you wish to use. Once JIRA is accepting new phone issues via the mail handler, you can setup a webform independent of JIRA to send these emails. It's possible to send these emails from Confluence by creating a page that uses the Form Mail Plugin, or use any independent page instead.
3. Adding Phone Information To Existing Issues
If you don't need to monitor phone calls closely then you may just like to add a comment to the existing issue. For more detailed information, you could create a phone call issue and link it to the existing issue.
