voip gw - sip box

[p.mafara]

Hello,

i'm looking for a documented solution to

connect two sites , i need a box to be put in front of an isdn bri pbx with 3/4 lines that can let the call exit to the isdn pstn or to internet sip in order to

connect to the remote site or other destinations.

Thanks and regards,

I've got already a sip proxy server , what i need its a box that could be a router , with 4 isdn bri to go inside to the isdn pbx , and 4 isdn bri to go outside to the isdn pstn , a voice call routing to decide wich number go to pstn and wich number goes to internet/intranet , of course if this box should also serve locally to handle sip phone like a pbx .
