[AusNOG] Telstra SIP/VOIP

[Paul Wilkins]

The PSTN exchange has the choice to either honour your CID as presented, or
to insert the CID the exchange is connected to. Which is to say, the fix is
to ensure your gear presents the correct CID, or trust to luck the telcos
will remap the CID, with results as you see.

Kind regards

Paul Wilkins
