plugins - How to send something from Dynamics CRM -

I would like to develop a way to send a text message (SMS) with Microsoft Dynamics CRM 4.0.

What would be the best way to do this? Should I develop plug-ins or use JScript and integrate it into workflow?

Thank you!

I think you want to archive messages in CRM. You can create a text message custom unit to store that data or modify an activity organization.

From there it depends on you is most comfortable. You can call web services either from JavaScript or custom workflow, a custom workflow allows for better testability and debugging, but there is more work to set up and install (not hard, just do more work).

My opinion: Use custom workflow.
