The last time I played with FreeSWITCH was 10 years ago, and now I'm helping a local nonprofit retire their obsolete analog phone system. I have a pbx system with 2 network cards: One dedicated to the phones, plugs into a PoE switch. On that network, the pbx has a DHCP server for the phones, as well as an FTP server for the Polycom SoundPoint IP 320 phones. The IP address on that network is 192.168.3.2. Since I'm setting up the system here at home, the other network card is on my Xfinity LAN, with an IP address of 10.0.0.167 (via DHCP from the Comcast modem). I understand the "domain" should be fairly fixed, so I set that to my "phone" network: <X-PRE-PROCESS cmd="set" data="phone_ip_v4=192.168.3.2"/> <X-PRE-PROCESS cmd="set" data="domain=$${phone_ip_v4}"/> <X-PRE-PROCESS cmd="set" data="domain_name=eastwest"/> I defined an sofia profile named "phone" with these lines: <param name="rtp-ip" value="$${phone_ip_v4}"/> <param name="sip-ip" value="$${phone_ip_v4}"/> I also used the default "internal" profile, in case an SIP device is hooked up to the main LAN, but that's not important. However, a "sofia status" shows this: Name Type Data State ================================================================================================= external-ipv6 profile sip:mod_sofia@ [2601:647:4802:9220:c816:30ae:6a9a:d191]:5080 RUNNING (0) 192.168.3.2 alias internal ALIASED external profile sip:mod_sofia@67.164.101.201:5080 RUNNING (0) external::sip2sip gateway sip:eastwest@sip2sip.info REGED external::flowroute gateway sip:6509889800@us-west-or.sip-flowroute.com NOREG phone profile sip:mod_sofia@10.0.0.167:5060 RUNNING (0) internal-ipv6 profile sip:mod_sofia@ [2601:647:4802:9220:c816:30ae:6a9a:d191]:5060 RUNNING (0) internal profile sip:mod_sofia@67.164.101.201:5060 RUNNING (0) ================================================================================================= 5 profiles 1 alias Why does the "phone" profile have "sip:mod_sofia@10.0.0.167:5060". Shouldn't that have the 192.168.3.2 address? And why isn't my phone registering? -- Steve
