The table below provides information on resultant system’s behavior, depending on the service policy options configured for both calling and called parties:
If a call party(s) is not assigned a service policy, PortaSIP processes the 18x responses for this party as defined in the convert_1xx option on the Configuration server. Thus,
- If the convert_1xx option is set to Yes, PortaSIP turns the 18x call progress responses and early media into a 180 Ringing message. This corresponds to the call_progress_filter option set to ringing_only.
- If the convert_1xx option is set to No, PortaSIP sends the 18x call progress responses without conversion and relays early media. This corresponds to the call_progress_filter option set to full_progress.
