[OpenSER-Users] ¿Se puede enviar DTMF durante el Early Media?
by Iñaki Baz Castillo 15 Jan '08

15 Jan '08

Hola, algo que fastidia a todo el mundo es el tema de que te cobren una llamada nada más salir el buzón de voz. Lo lógico y deseable (al margen de la actitud avariciosa de las grandes operadoras) es que al llamar a un número y salir el buzón de voz no se cobre la llamada y se ofrezca la posibilidad de dejar un mensaje pulsando algún dígito. El impedimento técnico que veo es que parece ser no se permite el envío de DTMF durante el EarlyMedia. Pero no encuentro documentación sobre ello. El caso es que durante el EarlyMedia el audio es bidireccional, o sea, el SDP del "183 Session Progress" dice: a=sendrecv (de hecho esto lo he verificado también a nivel de gateway PSTN: una llamada desde la PSTN a un gateway y éste la dirige a un SIP UAS que responde con 183, y el gateway envía y recibe audio desde el UAS). A todo esto una duda que tengo es precisamente esto de poder enviar y recibir audio durante un EarlyMedia, ¿se puede o no se puede? ¿se hace? Por otra parte, mi Twinkle no me permite enviar DTMF durante el EarlyMedia, pero vamos, que ni lo intenta por lo que no sé qué pasaría si sí me dejase. Y por las pruebas que he hecho llamando desde la PSTN (fijo y móvil) y respondiendo con un EarlyMedia, tampoco parece que se permita el envío de DTMF. En fin, que la única opción honesta que he encontrado es la de reproducir el mensaje del buzón en EarlyMedia, y sólo tras el mensaje responder la llamada para que el llamante deje su mensaje (y sólo en ese caso provocar que tenga que pagar su llamada). Con lo fácil que es... lo cab***as que son las compañías. Bueno, sin más, que no sé exactamente cuál es mi pregunta pero tal vez alguien me ayude a definirla XD Saludos. -- Iñaki Baz Castillo

[OpenSER-Users] Giving more power to CPL language: Addressbook Categories feature
by Iñaki Baz Castillo 15 Jan '08

15 Jan '08

Hi, in my opinion CPL language is not enough powerful, the absence of regular expression or any header reading makes it poor (IMHO). It would become really cool if it could match AVP's but it can :( I'm trying to give some power to CPL logic. I want to implement "addressbook categories" for each user, this is: each user has its own addressbook in which he can set a category for each contact: - Work - Friend - Family - Custom And of course what I need it a way to match that category **inside** the CPL logic. This is impossible with CPL itself so I'm thinking in a very very dirty trick: ** Addressbook Categories ** - In an incoming call for "bob(a)domain.org" OpenSer will match the callerid against Bob's addressbook. This will return a variable or AVP: $avp(s:caller_category) - CPL module just can match "Organization", "Subject", and "User-Agent", so OpenSer will do: append_hf("Bak_Organization: $hdr(Organization)\r\n"); # To preserve original Organization remove_hf("Organization"); # Remove original Organization append_hf("Organization: $avp(s:caller_category)\r\n"); # Set category as Organization - But since OpenSer appends/removes headers when the message leaves the proxy I can't run CPL now (it will not read the new "Organization" header), so I need to do a dirty loop in order to append the header. - When the message comes back into OpenSer the headers are updated so I do: remove_hf("Organization"); # Remove current Organization (that is a hack) append_hf("Organization: $hdr(Backup_Organization)\r\n"); # Restore original Organization (those changes will be applied again when message leaves OpenSer, not now). - And I run CPL: cpl_run_script("incoming","FORCE_STATEFUL"); - Into CPL I match "Organization" header by: <string-switch field="Organization"> <string is="Friends"> <reject status="reject" reason="I have no friends" /> </string> </string-switch> Is it enough dirty or could I make it more? Any suggestion? how do you people implement things like this? Thank a lot. -- Iñaki Baz Castillo ibc(a)in.ilimit.es

[OpenSER-Users] CRL/OCSP in OpenSer
by Jan Ruzicka 15 Jan '08

15 Jan '08

Hi, is it possible to use CRL (OCSP)? I found an old message from Klaus (http://www.nabble.com/-Users--CRL-in-OpenSER-to12712663.html#a12712666). As far I don't see mentioned new cfg parameter, I'm afraid its not possible. Are there any plan to use these features? Thanks Jan

[OpenSER-Users] OpenSER Configuration via files?
by Douglas Garstang 15 Jan '08

15 Jan '08

Asked this question earlier in the week, and didn't get an answer. I'm using avp_db_query to log calls to MySQL. I'd like to be able to turn this and other functionality on and off in the openser.cfg file without having to comment lines. Obviously putting the settings into MySQL and reading them with avp_db_query() doesn't make much sense. Does OpenSER have some sort of simple key/value pair configuration it read from a file so that I can control the basic configuration with? The db_text and db_berkeley modules are unfortunately only designed to be used for userloc data. Why is that? Thanks, Doug. ____________________________________________________________________________________ Looking for last minute shopping deals? Find them fast with Yahoo!

[OpenSER-Users] OpenXCAP: sphere and validity?
by KevinKinnan 15 Jan '08

15 Jan '08

I can't make it work when testing the effect of validity element in conditions element in Openser+OpenXCAP, also happen on sphere element and transformations. The presence document is based on rpid and it is quite simple. The only one I got it work is like below(without validity and sphere elements): <condition> <one id=""> </condition> <actions> <sub-handling>allow</sub-handling> </actions> The following two(adding validity and sphere) are not working: <condition> <one id=""> <validity> <from>...</from> <until>...</until> </validity> </condition> <actions> <sub-handling>allow</sub-handling> </actions> <condition> <shpere value="home"> <one id=""> </condition> <actions> <sub-handling>allow</sub-handling> </actions> Does OpenXCAP support these policies metioned above? Or, Openser is not supporting sphere and validity auth, it only knows sub-handling(xcap_auth.c in openser/modules/presence_xml)? Thank you!

[OpenSER-Users] avp_db_query() timeout
by Douglas Garstang 14 Jan '08

14 Jan '08

I haven't had much luck getting replies to my questions lately, hopefully I'll have more luck with this one. avp_db_query().... does it have a timeout? What is it? Can I set it? If I use it, and there is a MySQL database problem, I don't want avp_db_query() to wait forever trying to connect to MySQL. If it can't connect after a few seconds, I'd like it to just give up. I have multiple calls to avp_db_query() in a typical call flow. It would be even better if I could set a flag on the first timeout and not try again during that call. Can that be done?

[Serusers] xml rpc documentation
by Srinivas Kotamarti 14 Jan '08

14 Jan '08

Hi, Does anybody know where can I find more documentation on the new XML-RPC module of SER2. I want to write a management plugin for the application I am writing on top of SEMS using the XML-RPC interface. The documentation in the SER2.0 documentation page (http://www.iptel.org/rpc_xml_rpc) does not explain its full functionality and is not enough for writing a plugin. Thanks --Srinivas
