[Users] Behavior of next_gw
by Florian Fainelli 04 Apr '06

04 Apr '06

Hello, I would like to know what is the default behavior when using next_gw(). Here is basic example : A call is coming to gw 1, gateway no 1 rejects it, the next gateway is gw2, is this call forwarded to gw2 and so on ... ? Thank you very much in advance for your answer. Florian

[Serusers] Limiting number of calls
by Waldo Rubinstein 04 Apr '06

04 Apr '06

Is there a way to restrict the number of simultaneous calls for a particular sip client? For example, if I sell a service where each line can have at most 4 simultaneous call voice paths and there are two incoming calls and two separate outgoing calls, how can I make it so that whenever a new calls comes in or a user tries to make another call, they get fast busy or just busy? Thanks, Waldo

[Serusers] Anyone have config samples for asterisk-b2bua/SER?
by sip 04 Apr '06

04 Apr '06

We're looking into Asterisk-b2bua with SER to handle prepaid stuff, but we're running into the snag that, well, there's pretty much absolutely NO documentation for asterisk-b2bua. It's a few perl modules, a config file, and an INSTALL file that consists of explaining how to download the source and patch asterisk to use the program. That's it. It mentions radius, and it LOOKS like radius needs to be running on the same box as the asterisk-b2bua setup. I suppose that will work, as I can then point asterisk to do its accounting/auth on the SER box where I have radius running for auth. I've seen mention that asterisk-b2bua doesn't handle digest authentication (although it has an auth server in its config file), but I don't even know what it would be doing authentication FOR at that point and, since SER uses digest, I don't know how the two would mesh. Other than what I've been able to figure out from looking at the code (which is, granted, not a whole lot), there's nothing even remotely resembling docs (oh, my kingdom for the ability to force coders to hire technical writers). I was kind of hoping someone might have a sample config for use with SER... or be able to point me in the direction of one. N.

[Users] Mediaproxy and Prepaid/B2BUA interop issue!
by Dave 03 Apr '06

03 Apr '06

Hello,I have the following setup: UA<->NAT<-->SER/MediaProxy<->Prepaid(B2BUA)<-->PSTNGW | IVR Nat'd user calls a number that is forwarded (t_relay) to Prepaid and the user is prompted for PIN#/Destination Phone# and all works fine. Mediaproxy is invoked and a mediaproxy port# (35774) is assigned during the whole process. Once the user enters the destination number, the Prepaid forwards the call to the PSTNGW and the PSTN phone rings (Call signalling working fine). When the PSTN phone is answered, no media can be heard!!! I did some investigation and here is what is happening: Once the user enters the destination# to dial, The Prepaid/B2BUA does two things: 1) Sends a re-invite to put the UA on hold. 2) Sends an INVITE to the PSTN GW and retrieves the SDP from the response from PSTN GW 3) Sends a second-reinvite to the UA via SER with the SDP info of the PSTNGW 4) SER invokes the mediaproxy (since it is reinvite) and assigns the SAME MEDIAPROXY PORT# as earlier on when the media was flowing fine (SDP has audio port# 35774) 5) SER forwards the re-INVITE TO UA 6) UA responds with a 200 OK and sends 200 OK to SER. SER agains invokes mediaproxy and assigns the SAME MEDIAPROXY PORT# (audio port 35774) and forwards the response to Prepaid (which sends it to PSTNGW). I checked on Cisco PSTNGW that it is creating a session with the mediaproxy (port:35774). BUT NO AUDIO CAN BE HEARD IN ANY DIRECTION. Can anyone please help? Is this a mediaproxy issue that when reinvites are sent and mediaproxy is invoked multiple times, issues arise? I am running the latest mediaproxy version.

R: R: R: [Users] export SIP_Domain

Thanks. Do you think is possible, instead to work with script, to work over source code and change it to let it do what I want? Any thought? -----Messaggio originale----- Da: Daniel-Constantin Mierla [mailto:daniel@voice-system.ro] Inviato: giovedì 30 marzo 2006 15.56 A: D'Addelfio Davide Cc: users(a)openser.org Oggetto: Re: R: R: [Users] export SIP_Domain On 03/29/06 12:50, D'Addelfio Davide wrote: > Ok thanks, will take a look! > > Now that I've installed and running openser, I have to work over it. Do you know if is possibile to configure openser with some trigger that allows it to switch incoming message (INVITE, REQUEST, etc...) towards another element, like an application server? Do they exists? Where can I find it? > do you want to route certain request types to different hosts? Like if request is INVITE, send it to an application server? If so, then you can do: if(is _method("INVITE")) { t_relay("udp:app_srv_ip:port"); exit; } This example works with development version of openser, for versions 1.0.x below, check the documentation of tm module which is posted on project's web site (http://openser.org). You have to use the textops module as well.
