The location number field is optional, so you can follow the steps below to remove this from the outgoing IAM.Â
Â
1) Log into the webui then go to "Dialplan" as shown below to edit the dial plan. Once in the dial plan add the line "<action application="export" data="sip_h_X-FreeTDM-LOC=NULL" />" as shown below. The important part here is that it is before the bridge is done. The reason is the bridge line is what sends the call out the SS7 links. Once this is done click on the picture of the floppy disk at the top right to save the dial plan. Â
Â
2) Once this is done you will see the prompt below just click "OK" and this will apply the changes and will not effect any current calls.Â
