Indeed, I've found that you simply can't get multiple SIP devices behind a simple-minded NAT box without hacking their advanced configuration to run on different ports. Snag is some devices, e.g. Siemens S685IP dect voip+pbx phone, don't reliably allow fine-grained control of SIP settings. In the end I set up a small linux firewall with siproxd and then I was able to use a whole mix of Linksys PAP2T/SPA2002 and Siemens S685IP without issue. Set them up on a dedicated voice VLAN, add traffic prioritisation rules on the firewall and it works pretty well even over a domestic but good quality ADSL service. --------------------------------------------------------------------- To unsubscribe, e-mail: support-unsubscr...@pfsense.com For additional commands, e-mail: support-h...@pfsense.com Commercial support available - https://portal.pfsense.org
