Hi, I am looking at implementing SIP-based presence with PJSIP 2.0.1 in user applications. On user machines (Macs), I am running PJSIP in a daemon that services multiple clients (logons) each of which might have multiple SIP accounts. On a SIP server, I was hoping to validate and authorize specific SIP accounts using the 'SIP from address' in SUBSCRIBE requests. This would be the basis of enabling users to control who can subscribe to them (they wouldn't want to publish to just anybody). Am I correct in understanding that there's no way to set the SIP from address when sending a SUBSCRIBE message, i.e. calling pjsua_buddy_add() ultimately calls pjsua_acc_find_for_outgoing() which takes the first SIP URI server/port match with an existing account (setting the default account is, therefore, no help)? Thanks :-) -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.pjsip.org/pipermail/pjsip_lists.pjsip.org/attachments/20130215/2189ae80/attachment-0001.html>
