Hi Carsten,
The problem is solved, but with a litle bug. The calls from qutecom are
not relayed to sems.
Here is the solution:
failure_route[FAIL_ONE] {
#!ifdef WITH_NAT
if (is_method("INVITE")
&& (isbflagset("6") || isflagset(5))) {
unforce_rtp_proxy();
}
#!endif
if (t_is_canceled()) {
exit;
}
if (t_check_status("486|408")) {
avp_db_load("$ruri","$avp(s:email_address)/$email_scheme");
append_hf("P-App-Name: myvoicemail\r\n");
append_hf("P-App-Param:
Email-Address=$avp(s:email_address)\r\n");
append_branch();
fix_nated_sdp("1");
t_relay("sems_host","5080");
}
}
Thanks very much
Alejandro Mellado
