I see when we call to function to load the pstn gws:

$var(lcr_match_content) = "sip:" + $avp(s:first_caller_cli_userprov) + "@" +
$avp(s:caller_domain_netprov);

if(!load_gws("1", $rU, $var(lcr_match_content)))


Maybe you would prefer to match the subscriber against the NPN (network
provided number) instead of the UPN.

you could create a custom template for /etc/kamailio/proxy/proxy.cfg and in
ROUTE_PSTN change

$var(lcr_match_content) = "sip:" + $avp(s:first_caller_cli_userprov) + "@" +
$avp(s:caller_domain_netprov);

for

$var(lcr_match_content) = "sip:" + $avp(s:first_caller_cli_netprov) + "@" +
$avp(s:caller_domain_netprov);


That way you can always match against the cli of the subscriber no matter the
cli they use from the allowed_clis array. Would that work for you?
