When billing using different rate plans for incoming, outgoing and forwarded calls assign different access codes to the entries in the product’s Usage Charges configuration, for example:
- INCOMING – this tariff applies to calls that arrive at the PortaSIP server and end at one of your IP phones from both within and outside your network. The rating entry with this access code is also used to allow user SIP phones to register on the PortaSIP server.
- FOLLOWME – this tariff applies to forwarded calls and calls to a hunt group that are delivered by an auto-attendant.
- OUTGOING – this tariff applies to calls that originate from IP phones or customers’ gateways. Although you may specify an access code of OUTGOING, we recommend that you keep this entry as a “default,” e.g., leave the access code blank. This rating entry is also used to allow user SIP phones to register on the PortaSIP server.
- TRANSFER – this charge applies to all transferred calls (attended/unattended transfers).
The information above assumes that PSTN to SIP calls arrive directly to your PortaSIP server. If they arrive via the gateway on your network, replace INCOMING with a row containing your PSTN gateway, as explained in the Tips and Tricks. How to… chapter of the Unified PortaSwitch Handbook collection.
