I want to build a server which will act purely as a SIP proxy.
The idea is I will put the proxy into my DMZ, and on my internal
firewall I already have a Cisco 2600, which will convert the sip
traffic into something the pbx understands.
Can I do this with Ser?
Do I need to have MySQL installed, after all it's just a pure proxy?
Can I use it to create CDR's?
Any help appreciated.

Hi All
Does anyone know how to include a # in the following command
Prefix("123#4");
Because the above doesn't work. SER doesn't recognize the # and in fact
errors out on it.
I've also tried Prefix("123\#\4"); Prefix("123'#'4"); Prefix("123[#]4");
Thanks

Hi all,
does anybody knows if there's a way to
do something like music on hold with sems,
or if somebody is currently programing a plugin for it?
Thanks.

Jan,
Looking the logs hasn't revealed much telling info, but I'll go ahead
and send you what I have anyways. I took the liberty of extracting this
from my /var/logs/everything.log I was hoping there would be something
more helpful regarding that memory allocation error. I do know, after
looking at the source, that the "Can't allocate x-byte block" error is
coming from my particular xmlrpc-c library. Interestingly enough I have
a generic xmlrpc-c.tar.gz which does indicate very well what version it
is on. Looking at the sourceforge page all of them have a particular
schema which has left me wondering where I found this package. I am
going to assume that it is ver 1.03.02, but I am going to go ahead and
update it to see what happens, since there was a new release yesterday.
I will let you know if that error persists after the update.

The problem with NAT is because the IP address of the SDP body is a
non routeable IP. So how does a media proxy works?
I read that a media proxy put his address at the sdp body and both UA
talks with the media proxy instead of each other. At the time a NAT
user sends an INVITE, there is no corresponding port on the NAT. So
How does a media proxy contact the NATed UA?
Isn't this the same problem the called part will have to contact the
NATed party?
I read a couple of papers about it, but in all of them it is said that
both ends talk to the media proxy and that is all. No explanation
about how things work. I know it works because I am using mediaproxy.
If anyone could point me how this works or where I can find a document
explaining....
Thanks,
Felipe

Hello,
How can we use ser and rtpproxy for load-balancing and
failover ?
if ser is able to handle n calls per second how can we
calculate the load for rtpproxy ( memory, cpu, ...)
in order to send all traffic to one rtpproxy?
If this one is down nathelper module is able to send
traffic to an other rtpproxy .
SER-----------------------------
| | |
rtpproxy1 rtpproxy2 rtpproxy3
via unix socket
What's the best way for SER failover ?

Hi Matt,
I redirected this email on the users mailing list - it's more appropriate.
the idea seams ok, with couple of comments:
1) be sure that fwd to localhost is ok (instead of a routable IP)
2) doing Record-Route may be a good think.
to debug tour problem, add some log("...") statements into your script
to be able to trace the processing. Also a network trace (including on
lo device) will be helpful to see what happens - if the messages are
received, if they are sent and where. Also watch the log for potential
errors.
regards,
bogdan

Hello,
I think that most of the ser users would wish a
roadmap for SER ?
Does team developpers could provide it ?

Harry
