Custom Tag
The custom tag field on Call Detail Records (CDRs) is populated from the optional X-Tag SIP header field, which you can specify on each outbound call. The maximum length you may use for this field is 32 characters; anything longer will be truncated. You can populate the contents of the custom tag dynamically using variables if you're a savvy user for your respective system. This allows you to tag CDRs with your internal customer IDs, calling campaigns, etc.
This article describes creating custom tags for Asterisk, and FreeSWITCH.
Asterisk
Add the following line to your dial plan before the Dial() command to tag your calls with a custom tag. In the following example, bob is added as a custom tag. SIPAddHeader(X-Tag: bob)
FreeSWITCH
Add the following to your dial plan XML for outbound calls to add the custom tag. In the following example, bob is added as a custom tag. sip_h_X-Tag=bob
For inbound calls, add the following for the custom tag. In the following example, bob is added as a custom tag. sip_rh_X-Tag=bob
