Your remark about digest authentication explains why I have had difficulties. I was considering merging SIP interconnects with digest authenticated SIP trunks in a single gateway. I would prefer not to use a B2BUA as a PSTN gateway in order to avoid carrier media where possible. I suspect it might be better to separate out any digest authenticated SIP trunks to a B2BUA just for this.
My main reason for wishing to run a back-end gateway is to simplify our own network and to be able to reconcile against third-party CDRs all in one place. Can you point me to any documentation for running Kamailio as a PSTN gateway?
