SIP yes. Since there might be downstream or upstream proxies which are dual stacked and record-routes and vias might turn up IPV6. sipX has done a good job not to barf when receiving them. SDP is a bit different since it directly hits sipx via sipXrelay and an IPV6 offer even if coming from a IPV4 hope will definitely be trouble. _______________________________________________ sipx-users mailing list [email protected] List Archive: http://list.sipfoundry.org/archive/sipx-users/
