Sorry if this topic is covered already but I can't find an answer...
I want to connect an IP phone (either hardware or softphone) to the SPA9000 from internet (not via VPN)
Firstly my SPA9000 is behind NAT firewall. This firewall is configured to direct UDP port 6060 to the IP address of the SPA9000. I can setup softphone such as X-Lite and PhonerLite within the LAN and it works fine. However if I setup from Internet location the phone registers ok and a dialed extension will ring but when picked up neither party can hear eachother?
NAT Support Parameters
Handle VIA received: Yes Handle VIA rport: Yes
Insert VIA received: Yes Insert VIA rport: Yes
Substitute VIA Addr: Yes Send Resp To Src Port: Yes
STUN Enable: No STUN Test Enable: No
STUN Server: EXT IP: xxx.xxx.xxx.xxx (external ip of firewall)
EXT RTP Port Min: NAT Keep Alive Intvl: 15
Stun Server: [blank]
password: [Phone ext password] as defined in SPA9000
softphone shows: sip:[email protected] Registered
Any help is greatly appreciated.
