I would agree, at one point I was taking calls on asterisk etc, but its
the wrong way of doing it, get ser to do all the donkey work, and then
use asterisk or whatever b2bua to take care of billing, if like me you
need voicemail etc, then just use asterisk to do both function..
Using ser you can redirect to various backend asterisk boxes to help with
scaling, and in the middle also take care of the mediastream, and
natting issues.
As for the pstn , just either handoff from ser, or you could habd off
from asterisk (waste), if u want toi manipulate callerid, let me know
how also, cause I am having the same problem, ser really cant do it,
since it does not maintain state, hence I am thiking of having a special
route for calls who need to have CLID changed, route them to asterisk
get them changed and then forward them to a SIP device...this sounds a
bit crazy but I cant see how else to do it
Now if someone can just tell me whats the easiest way to debug calls, I
have logs logs and more logs, but it never makes sense...well not easily
because of the multiple invites etc, tracing one call path...there must
be a way

But why do you need SER in this case? that gonna be extremely unscallable
system (not because of SER but because of asterisk). You can use simple
asterisk to get same functionality.
In my system, SER is registrar and NAT traversal (you need it to do SIP-SIP
calls). Then I have b2bua to do CDR and digit manipulation and then it goes
to termination carrier
Asterisk as b2bua is kind of expensive in my opinion. Not so stable and take
a lot of resources. Whenever I send call thru Asterisk I notice that overall
quality go down. May be it just because I do not like asterisk :)
If you in your setup will do same as in mine but instead of B2BUA use
Asterisk, then it will be scalable quite nice by just increasing amount of
asterisk servers

Subject: Re: [Serusers] SER+Asterisk on high loads
How about the following scenario:
One box acting as a proxy to a PSTN. Asterisk is handed the initial
request (port 5060) in order to do some modifying of the packet
(callID), and to keep a stateful connection for CDR's. Asterisk passes
it to SER (port 5061 on the same box) which uses its logic to route the
call to one of several PSTN's. All of this is done in g729.
Why do it this way?
SER cannot modify the callID without having issues.
I don't trust SER to do the CDR, and logging on the endpoint is very
difficult compared to Asterisk.
Any idea what the load maximum would be with that same P4 3.X/Xeon?
Best regards

I would never recommend to have asterisk and ser on one machnine, asterisk
that will work on separate machine with P4 3.X/Xeon terminationg calls to
PSTN can handle up to 100 calls easily.
SER with rtpproxy on one server can handle REGISTRATIONS from 10000
clients.
Even if they will do it every 30 sec (depend of
course how u gonna
authenticate them)
RTPPROXY can handle much more then 100 calls (what codec btw ?) plus you
can
distribute SER to different machines to work in a
cluster OR you can use
mediaproxy or nathelper in same cluster mode.
Btw, I believe you not gonna let all calls trough asterisk ? asterisk is
only for termination to PSTN ? otherwise forget what I wrote :)

Hello, All!
There is some questions about subj.
With what loads SER+Asterisk can be used? I need to know, what number of
simultaneous registrations and simultaneous calls can handle this
conplex? It'll be very good, if someone can say his success story about
SER+Asterisk.
Now, we're planning 1000-10000 clients... can SER handle this number of
registrations? And can SER+Asterisk (assume that almost all users are
using NAT) can handle calls of 0.1-1% of above clients base?
Great thanks to all for answers.
