B2BUA (SBC) $2500
$2500 Bounty for a Back-to-back user Agent (SBC) addon that would work with sip trunk providers like www.bandwidth.com, www.bandtel.com and www.bbcom.com (IP only).
1. This B2BUA should be able to handle all incoming and outgoing calls
2. Forward all calls to an internal SIP IP-PBX (sipx www.sipfoundry.org, asterisk www.asterisk.org)
3. Have an optional failover option
4. work with the current QoS module on pfsense
5. Allow phones at remote location to register with the IP-Pbx behind NAT on both ends
I'm interested in solving this. Is it still available?
