[asterisk-users] Obtain SIP From and To Tag for CDR

[Robert Thomas]

List,

I'm trying to obtain the Call ID, From tag and To tag of the SIP calls from
Asterisk, to store them on a CDR and be able to conciliate with another CDR
system ( opensips )

I have been able to obtain the SIP Call ID CDR(sip_callid)=${SIPCALLID}

I was wondering if there's any way to obtain the From and to tag.

Asterisk 1.6.2.9 and 1.8.5rc1

Thanks,
-- 
Robert
