Hello guys,
many thanks, you were right :)
I changed the PAI and the RPID stuff and it works ...
-- KAMAILIO --
# flag 9 = clir
if (is_avp_set("$avp(s:caller_cli)/s") && !isflagset(9))
{
if (is_present_hf("P-Asserted-Identity"))
{ remove_hf("P-Asserted-Identity"); }
if (is_present_hf("Remote-Party-ID"))
{ remove_hf("Remote-Party-ID"); }
append_hf("P-Asserted-Identity: $avp(s:caller_cli)
<sip:$avp(s:caller_cli)@$fd>\r\n");
append_hf("Remote-Party-ID: $avp(s:caller_cli)
<sip:$avp(s:caller_cli)@$si>;party=caller;privacy=none;screen=yes\r\n");
}
Do you have a better solution to have the best rpid and pai coding way ?
And, is the P-Preferred-Identity really necessary for PSTN ?
log in the gateway :
