Transparent IAM
When the Transparent IAM feature is enabled, on incoming calls, all the information received in the incoming IAM message are stored inside a channel variable. This allows the IAM message to be transmitted out with the exact same information if needed.


Parameter Name:transparent_iam
Possible values: yes/no
Default value:no
example:
Source file
<cc_span name="p1s1"> <param name="id" value="1"/> <param name="isup_interface" value="1"/> <param name="cicbase" value="1" /> <param name="ch_map" value="s1,2-31"/> <param name="typeCntrl" value="controlled"/> <param name="transparent_iam" value="yes"/> </cc_span>
SIP Headers
For transparent IAM to work, your target SIP gateway needs to passthrough the X-FreeTDM-IAM SIP header to the b-leg of the call.
For example, if using Asterisk:
in /etc/extensions.conf:
[from-smg]
exten => _X.,1,SIPAddHeader(X-FreeTDM-IAM:${SIP_HEADER(X-FreeTDM-IAM)})
