I'm sorting out a VOIP setup for the office that I work in (there's about 50 people, mostly macs), and I'm looking for a good SIP softphone that would work with an Asterisk based PBX, and I figured others might be looking for something like this too.
I'm after the usual staples:
- handling multiple sip accounts
- conference calling
- caller id
- ldap/address book integration
- uses SIP
What do you guys use?
