I don't doubt that you're right, Daniel. I have asked for some assistance on the PJSIP mailing list, as I get the same error from both Asterisk 13 and CSipSimple nightly build. Since Asterisk has moved to PJSIP, this could pose a significant interoperability issue. http://lists.pjsip.org/pipermail/pjsip_lists.pjsip.org/2015-April/018313.html Thanks again. -A -- Anthony - https://messinet.com/ - https://messinet.com/~amessina/gallery 8F89 5E72 8DF0 BCF0 10BE 9967 92DC 35DC B001 4A4E
