I believe you should enable siptrace and review the messages sent by the provider. (This is the same method that I used to determine the proper field/information element send by CallCentric containing my DID so that I could route the call properly in my dialplan.) In fs_cli type sofia global siptrace on -- or -- sofia profile sillytel siptrace on /* assuming the sip profile used to reach your provider is named "sillytel"; this eliminates extraneous SIP messages from your trace */ Now place test calls inbound or outbound or both as needed. When you have seen enough type sofia global siptrace off You then have much homework to do :-) --- Bote FreeSWITCH Docs Janitor http://freeswitch.org/confluence

I've registered with SIP-trunk providers for experimentation.

How can I figure out which codecs a SIP-trunk (gateway in FS parlance?) provides?
