Hi. I am using firmware 8.5(4) SIP. I see the register message on the FreeSwitch machine using ngrep. Everything seems ok, but I get unauthorized. Then I thought to myseld that this might be NAT issue. So I tried setting up a Asterisk on the same subnet as the telephone is sitting on. Same result. I have taken some info out of security reasons. Theese are marked in red text. The ngrep log below is from the FreeSwitch machine. I have also read from zero to hero here. http://www.freeswitch.org/node/401 The two first link give description of how to setup a TFTP server and soforth. I already have this. Important to mention that the Cisco 7942 is a newer phone than in theese first two links so to get the relevant config look at the third link. Below is the third link from this page. Have used lots of info from this page. http://www.voip-info.org/wiki/view/Asterisk+phone+cisco+79x1+xml+configurati... A little snippet from the console log on the phone. 977: ERR 09:43:30.785766 JVM: dns_gethostbysrv 3 h_errno 978: ERR 09:43:30.786378 JVM: sipTransportGetServerIPAddr: Error: sipTransportGetServerAddrPort returned error. 979: ERR 09:43:30.803646 JVM: dns_gethostbysrv 3 h_errno 980: ERR 09:43:30.804270 JVM: sipTransportGetServerIPAddr: Error: sipTransportGetServerAddrPort returned error. 981: ERR 09:43:30.821237 JVM: dns_gethostbysrv 3 h_errno 982: ERR 09:43:30.821830 JVM: sipTransportGetServerIPAddr: Error: sipTransportGetServerAddrPort returned error. 983: ERR 09:43:30.838442 JVM: dns_gethostbysrv 3 h_errno 984: ERR 09:43:30.839066 JVM: sipTransportGetServerIPAddr: Error: sipTransportGetServerAddrPort returned error. 985: ERR 09:43:30.856124 JVM: dns_gethostbysrv 3 h_errno 986: ERR 09:43:30.856715 JVM: sipTransportGetServerIPAddr: Error: sipTransportGetServerAddrPort returned error. 987: ERR 09:43:30.874024 JVM: dns_gethostbysrv 3 h_errno 988: ERR 09:43:30.874615 JVM: sipTransportGetServerIPAddr: Error: sipTransportGetServerAddrPort returned error. 989: ERR 09:43:30.891639 JVM: dns_gethostbysrv 3 h_errno 990: ERR 09:43:30.892265 JVM: sipTransportGetServerIPAddr: Error: sipTransportGetServerAddrPort returned error. 991: ERR 09:43:30.908952 JVM: dns_gethostbysrv 3 h_errno 992: ERR 09:43:30.909538 JVM: sipTransportGetServerIPAddr: Error: sipTransportGetServerAddrPort returned error. 993: NOT 09:43:30.985443 JVM: Startup Module Loader|cip.midp.midletsuite.InstallerModule:? - propertyChanged - device.callagent.messages.0 value=0 994: NOT 09:43:30.988054 JVM: Startup Module Loader|cip.midp.midletsuite.InstallerModule:? - propertyChanged - device.callagent.messages.0 value=0 995: ERR 09:43:31.002746 JVM: dns_gethostbysrv 3 h_errno Best regards Andre U public_ip_office_network:3197 -> ip_of_the_pbx_public_ip:5060 REGISTER sip:dns_name_of_pbx SIP/2.0.
