Outgoing Call Routing for a Trunk Group

Outbound calls on a trunk line are handled as follows:
1. When a PBX phone selects an outside line, the PBX looks for an open line. If the PBX finds an
open line, it takes the line off hook and bridges the audio between the PBX phone and the
line. On detecting the off hook signal, the SPA8000 Line UA plays dial tone and ready to
collect digits from the PBX phone.
2. As the PBX phone user dials the number, the Line UA applies its dial plan to the number. If
the Line UA detects an invalid number, it rejects the all by playing reorder tone, then
howling tone, then silence. If a valid number is received, it sends a SIP INVITE message to
the internal Proxy.
3. The Proxy routes the call to the trunk group UA for the line, and the trunk group UA will
attempt to place the call to the ITSP if there is available capacity on the trunk. If there is no
call capacity left on the trunk, the internal Proxy will reject the INVITE from the Line UA,
which in turn terminates the call and plays reorder tone out to the FXS port.
