Hi, I tried every combination of trunk names, in order to register the trunk from planetphone.net. I tried the IP address (82.103.114.37), but no luck Register string: userid:password@sip.planetphone.net/userid (I named the trunk with my USERID to do it) PlanetPhone.net requirement for outbound: username=userid type=peer qualify=yes secret= password nat=auto insecure=very host=sip.planetphone.net fromuser=userid fromdomain=sip.planetphone.net dtmfmode=rfc2833 context=from-trunk disallow=all allow=alaw&ulaw&GSM inbound: username=userid type=user secret=password nat=auto insecure=very host=sip.planetphone.net fromdomain=sip.planetphone.net dtmfmode=rfc2833 disallow=all context=from-pstn allow=alaw&ulaw&GSM
