I have pstn (isdn) gateway 192.168.0.163, and I make calls using prefix "8"
Here's a log from a local call (using CiscoATA186 and Wu-chuang Sipphone):
Apr 7 20:49:09 domenet /usr/sbin/ser[18289]: ACC: transaction answered:

And here's a log from calling to pstn (using Wu-chuang sipphone and pstn
gateway) to number 0506633351 (isdn:506633351) :
Apr 7 20:52:54 domenet /usr/sbin/ser[18284]: ACC: request acknowledged:
method=ACK, i-uri=sip:8506633351@192.168.0.163:5060,

As You can see, there's no BYE message ,but only if the pstn-side
disconnects. If the LAN side disconnects, theres a succesfull BYE message.
I use forwarding to pstn using the loop:
if (loose_route())
{ t_relay(); break;
}
if (method=="INVITE") {
record_route();
};
setflag(1);
if (uri=~"^sip:8[0-9]{3}@*") {
log(1, "Forwarding to ISDN...");
rewritehostport ("192.168.0.163:5060");
t_relay();
log(1, "..forwarded\n");
break;
};
Moreover, calling PSTN there's only silence in LAN's side, although PSTN
hear LAN very good.
Where am i wrong ?
