According to draft-ietf-sip-isup-03.txt " The construction of the From field is dependent on the presence of a CIN parameter. If the CIN is not present, then the gateway should create a dummy From header containing a SIP URI without a user portion which communicates only the hostname of the gateway (e.g. 'sip:gw.level3.net')." This works fine in case of a GW-GW scenario as the originating GW will send only the IP Address in the From field and the terminating GW will remove the IP Address before sending the CIN to the SCN network. But in case the call lands on a SIP terminal from Gateway then From field will not reflect the calling party who is the subscriber of GW, rather the SIP terminal might just display the IP Address of the GW as the calling party number on the user's screen. So Wouldn't it be better to add sip:Anonymous<[EMAIL PROTECTED]> ? This way the SIP User will display the display name as Anonymous. But ofcourse, a limitation of this will be in the GW-GW scenario, the terminating GW might map it to CIN presentation restricted while sending it to the SCN n/w. Any suggestions??
