Mitel 5000 and CPN Substitution? 1

[vlevalois]

Does anyone know if there's a way to have CPN Substitution with a PRI connected to the Mitel 5000?

Thanks!

Depending on how flags are set, each phone, CO trunk group and/or SIP peer trunk group can be programmed to send an identifying number when a call is placed. This is called the "Calling Party Number." (This information is required for emergency calls in some states.) You can program any number up to 48 numeric characters (up to 15 alphanumeric characters, except for :, “, and “ for a voice mail or SIP voice mail application) in the Calling Party Number field. However, check with your service provider to determine their specific requirements for this field. This number will be sent in the ISDN or SIP setup message in the Calling Party Number Information Element. In addition, the system will also send the extension number of the phone in the Calling Party Number Subaddress Information Element. The CO (local exchange) should ignore this information element if it does not support it. In the case of SIP, it will influence the "From," "Contact," and "P-Asserted-Identity" fields in the SIP headers.
