I have a problem with redirection to voice mail. If caller hangs up,
the CANCEL hits SER and the call is cleanly terminated. SER however
continues to failure_route after timeout of the initial INVITE which
results in an empty message generated by the voice mail server.
Does anyone know how to deal with this?
Thanks,
Adrian
if (is_user_in("Request-URI", "voicemail")) {
setflag(3);
};
if (!lookup("location")) {
xlog ("L_INFO","Location not found");
} else {
if (method == "INVITE" && isflagset(3)) {
xlog ("L_INFO","Flag3 is set, try voicemail after timeout");
t_on_failure("3");
};
};
xlog ("L_INFO","Relay to destination");
xlog ("L_INFO", "%rm from %is: %fu -> %ru\n");
t_relay();
--------
failure_route[3] {
revert_uri();
xlog ("L_INFO","Forward to voicemail (failure route 3)");
exec_dset("/etc/ser/serredir.py voip_voicemail ;echo>/dev/null");
append_branch();
t_relay();
}
Consider the situation whereby after an INVITE occurs which ser initially
routes to A (which is, say, busy) and subsequently routes to B. Perhaps it
has gone through t_on_failure or some other mechanism of sequential
forking. Assume the INVITE has been OK'd and ACK'd.
What mechanism does ser use to ensure subsequent transactions on the
call-leg (such as BYE, re-INVITE etc.) are sent to B and not A? IE where is
the state being stored and how?

hello friends,
iam having stable ser cvs version
in redhat linux 9.0
i used the rtpproxy for quite some time
to test between public ip - private ip but could not
get success.
so now iam testing with mediaproxy
so as instructed in the install file of the
mediaproxy it s not starting any procees
and when i press ps -f | grep "mediaproxy.other"
its not showing any process running
if i start individualy the files like
-------------------------------------------------
[root@server mediaproxy]# ./mediaproxy.py
Traceback (most recent call last):
File "./mediaproxy.py", line 21, in ?
from optparse import OptionParser

Klaus,
Thank you for your help. I have got a working ser.cfg and the system
forwards the voicemail to the voicemail platform. I can also forward my
internal calls to my Asterisk box and all is well.
I seem to have problem with the nat_helper module.
I'm using the version that comes with 0.8.12 rpm;
I get the following in the debug;
0(9285) find_export: <nat_uac_test> not found
0(9285) find_export: <nat_uac_test> not found
0(9285) parse error (113,22-23): unknown command, missing loadmodule?
This is related to the following chunk of code;
#if (nat_uac_test("2")) {
# log(1, "src address different than via header->NAT
detected\n");
# log(1, "force_rport and fix_nated_contact and
setflag(5)\n");
# #try NAT traversal, works only if the client is symmetrical
# force_rport();
# fix_nated_contact();
# append_hf("P-hint: fixed NAT contact for request\r\n");
# # flag 5 indicates that incoming request is from NATed
client
# setflag(5);
#};
I comment this out and all seems to work. I'm very interested in using the
NAT helper module.
Warm Regards and Thanks
Shad

Hello:
With 0.8.12 the MySQL GRANT statements in the create database
section of ser_mysql.sh didn't seem to work. Both ser and serro from any
host or localhost have no privileges. Is this a known issue? If so is
there a fix?
Thanks,Steve
Hi Girish!
Please send all emails to the list.
I have not tried IVR yet, nor I'm a programmer and experienced in
debugging - so my advices are very basic.
As ser crashes not immediately, maybe this is a memory problem. Try to
comment some parts of your module to find out the statements which makes
ser crash.
regards,
klaus

Hi All,
Could some one tell me what the version status and compatibility is with
ser and sems?
Is ser 0.8.12 compatible with the cvs version of sems?
If not, are there plans to make new releases of ser and sems that will
be compatible?
Thank you,
-Jev
Hi,
User 1000 calls 1001, who is cfwd (302) to a pstn number. Pstn provider will see 1000 as the caller and he get billed
for the call to pstn. Is there a way to insert 1001 in the Remote-Party-Id header in this scenario to fix billing info?
Something like: if (method == "30X"), extract number from "To: header" and insert it as Remote-Party-Id?
Thanks,
Tor.
Hello Everyone,
is there any reason for the lookup("aliases"); function not working on the
last CVS version (0.8.13-dev-29) neither on the version
0.8.13-dev-27-sockunix?
Best Regards,
Toni
