kamailio or opensips?

kampung

Hi All, Can someone give some recomendation for SIP server?

I have use both of opensips and kamailio, but only for basic usages: - support regular sip phone (sflphone, ekiga, xlite) - support sipml5 - (not so smooth) integration of opensips & asterisk.

I want to leverage my usages: - add some security - integration with freeswitch - user authentication with external authentication (maybe to external CMS/django/LDAP or whatever) - integrate with PSTN, if possible.

My thinking about kamailio and opensips: - it seems kamailio has more features - there is an opensips book, no kamailio book - more irc user in opensips channel - more mailing list users in kamailio

Any suggestions?

Thanks
