I've had this problem too, especially running syslog debug or external
processes. what ver of ser are you running? We had to ditch a lot of our
external processes because I assumed they took too long to run, no one
on the list was any help so I just gave up. Not being a coder is very
frustrating..

Subject: [Serusers] SER stops responding
I am having a strange problem with 0.9.0. At random times, SER will just
stop responding. I run ethereal, and can see INVITEs, REGISTERs and
OPTIONs requests, but SER does not respond to any of them. The process
does not die, and moni tells me that SER is still running, just no
respones. Sometimes SER will recover after a few minutes, most of the
time it doesnt. Any ideas?

I'm using proxy_authorize function but something goes wrong because I check also
whether user is in defined group to make calls. In other words if sip proxy w/ ip 12.34.56.78
forwards traffic to sip proxy w/ ip 10.10.10.10 and user:1234@12.34.56.78 doesnt exsist
in 10.10.10.10 group table it's call is rejected.
Thanks,
Pavel

Subject: [Serusers] How to authorize sip proxies
Hi there,
Can you help me how to stop other sip proxies to forward calls to my ser and
how to authorize some of them to forward calls to me.
Thanks and regards,

Hi everyone,
It seems that ser-0.8.14 will become "dead" after running for a few days. I am using rtpproxy and nathelper with ser. After I restarted ser and rtpproxy, everything becomes fine again.
Would this problem be caused by ser-0.814 or rtpproxy? I don't know ser-0.814 or rtpproxy will be stable or not. Have you encountered such problem?
Also, is ser-0.9 more stable than ser-0.8.14?
Best Regards,
Thomas
Hi,
I'm trying to register my sip application to the SER
Register using MD5 authentication but I don't know
what parameters I had to concatenate to make the
response, and how to cancatenate it. If someone can
help me. Thanks.
I have readed something about the MD5 of
(username+password+nonce+method+uri), but concatenated
with a point?
Is my first time with the authentication ... :P

I have SER and one Cisco 7960 phone in public network.
One cisco 7960 in a private network behind NAT. I have
configured SER with nathelper and rtpproxy (both are
downloaded via CVS).
Call from public to private network works fine. But
when I call from private to public network, then phone
rings fine, but there is no audio.
I'm wondering how can I get both ways to work ? I have
just one ser-server, do I have to two servers, which
one is proxy and another is used as outbound proxy.

Dear ALL:
I have defined these lines at my ser.cfg.
modparam("avpops", "avp_url", "mysql://ser:heslo@localhost/ser")
modparam("avpops", "avp_table", "usr_preferences")
modparam("avpops", "uuid_column", "uuid")
modparam("avpops", "username_column", "username")
modparam("avpops", "domain_column", "domain")
modparam("avpops", "attribute_column", "attribute")
modparam("avpops", "value_column", "value")
modparam("avpops", "type_column", "type")
modparam("avpops", "avp_aliases",
"voicemail=i:500;calltype=i:700;fwd_no_answer_type=i:701;fwd_busy_type=i:702")
Q1: But I don't know what it mean about 700 or 701. Is it a numeric ID
of one UA?
And I have refered to http://www.voice-system.ro/docs/avpops
And find many examples in it.
But I still can't understand what it mean about avp_db_load().
my avp table is named as "usr_preferences" and it is empty before I
use avpops modules.
Q2: Is it should have some initilized records in it?
Otherwise, what will be loaded with avp_db_load()?
For this web page said:
avp_db_load("$ruri/domain","i:/domain_preferences");
- loads all AVPs with ID from 'domain_preferences'
table for domain from RURI
Q3: Is "$ruri" the caller user's URI? and the "domain" is the same?
Is "domain_preferences" table name? Is it equal to my "usr_preferences"?
Or it is just a virtual table in memory?
Thank you for your answer my stupid questions.
Charles
Thanks Marian's help and answer. I can make a call from domainA to
domainB via PDT module.
But I got another error message from nathelper or rtpproxy.
It is "ERROR: extract_mediaip: no `c=' in SDP" from /var/log/messages.
I also find this message at source code of nathelper. So I think it
should happen from this module.
It seems voice channel can't pass throught it.
I make a call from UA_A ( under NAT ) from domainA and using PDT to
redirect to UA_B via domainB. UA_B has ring and it can answer. I can
hear the UA_A's sound from UA_B. The sound of UA_B is failed to UA_A.
UA_A(NAT) ==> domainA(PDT) ==> domainB(nathelper+rptproxy) ==> UA_B(NAT)
SOUND_A ==========================================> UA_B
UA_A <===== XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX === SOUND_B
Do I put the prefix2domain() in a wrong place?? Or Is it a bug ofi
nathelper & rtpproxy?
And my ser.cfg as below:
Best Regard.
Charles
