Hi,
Upgrading to version 4 gives you some advantages:
- Version 4 could be redundant in real time, not only in 'Cold StandBy' mode. You could have two servers at the same time and if one falls down you will have inmediately a backup one.
- You have a wrap up time out.
- The java interface is more powerful than in version 3. Ypu can add java in the expression editor easily.
- The system scalability is much better than in version 3.
- You will have support for upper CallManager versions (4.2).
- You can send calls direct to an agent.
- You have more choices in the CSQ skill selection.
These arer some features than you can get with version 4 of IPCC Express.
Hope this helps,
Juan Luis
