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?
Thanks
Rob

It depends on what features you need facing the
gateway providers. Eg. if
the gateway provider uses digest authentication then you may run into
problems with Kamailio. Many people use a B2BUA as "fake" gateway to have
full control over the call (e.g. Asterisk, sems, sippy)
