Hi, To help some UA for NAT I need set <variable name="sip-force-contact" value="NDLB-connectile-dysfunction"/> <param name="NDLB-force-rport" value="true"/> in user profile，however looks like the NDLB-force-rport doesn't work in a per user way, when I set in profile settings it works. 1) So questions is, is it possible to make it work a per-user way? I don't to do the risk to set it on a profile for all users. 2) Also, another question, looks both params fails to work when FS is behind kamailio(maybe opensips), my settings is: kamailio at the front listening at 5060 and forward anything to 5070 - the FS internal profile rewriteport("5070"); route(RELAY); exit; I'm not a kamailio guru, any possible way to make it work behind kamailio? Or should there some equivalent module/params in kamailio for this behavior? Thanks. -- About: http://about.me/dujinfang Blog: http://www.dujinfang.com Proj: http://www.freeswitch.org.cn Sent with Sparrow (http://www.sparrowmailapp.com)
