Voip bridge to Voip

Hi guys,

we have a voip in our country that lets u call nationwide to any PSTN and Cell for a very low price. I have an ATA186 connected to a 256kbps ADSL with static ip.

is it possible for me to connect my mother in the U.S. to my voip device and account.

it will be something like

my local
US–>DSL–>(???)–>ata186–>VOIP

(???)- can be a any device to add

the procedure to call on our loacl voip is, pick up the fone attach to the ata186, prompt will ask u to enter the Tel#, u enter the number with the #, then it connects to the destination.

would like my mother in the U.S. to have the dial tone form my ata186 and the prompt to enter tel#
