We need to replace our current simple SIP client (X-lite) with custom developed SIP client in order for it to have specific features we need:
Some of the features we plan:
- shared contacts (if agent A creates a new contact, agent B can use it)
- central call log (all agents see all calls)
- in case the call is answered, a customer profile pops up (simply a browser is opened/brought to foreground: http://server.com/profile/{callerid})
Are there any open-source SIP clients (or libraries) which could be extended to support those features?
