hello
thanks for your answer...
after testing... it's not working at all i'v done the 2 test but do not working...
i thinks that simply voxalot is not compatible with the provider...
i will use my spa-3102 in supplement of my WRT54GP2 to use this provider like a want with an ajusted dialplan...
i could not tell you what is the provider name because normally i don't have access to my account details (user name, pass, proxy, etc.)
it's possible too that the provider block diffrent ip from mine to register the service...
or voxalot is not compatible with provider that use proxy and outbound proxy to register...
any way thanks again
