Sorry for the delay. I did not read your reply. Nice solution. I need to check that IOS based pbx can read a custom header. Regards.

[OpenSER-Users] [OT] How to handle different DID's in incoming calls for a registered client?
by Iñaki Baz Castillo 27 Feb '09

27 Feb '09

Hi, maybe this question is a bit off-topic so I'm sorry for that. My question is about SIP providers using OpenSer that associate PSTN numbers to their local clients (SIP accounts): Usually the client must register to OpenSer in order to receive calls. Then it will appear in location table with "Contact=sip:clientX@IP". Suppose clientX has two PSTN numbers associated in a ENUM entry: +34999000111 +34999000222 When anyone in PSTN world calls to +34999000222 the call will arrive to the OpenSer from a gateway in an INVITE like: INVITE sip:+34999000222@gateway SIP/2.0 To: <sip:+34999000222@gateway> The OpenSer will do the lookup in location table and finally send this INVITE to the clientX: INVITE sip:clientX@IP_clientX SIP/2.0 To: <sip:+34999000222@gateway> The info about the called PSTN number is just available in "To" header, so a way to get different behaviour for each associated PSTN number is matching "To" URI. Is common to do it? which other alternatives are there? Thanks for any comment. Regards. -- Iñaki Baz Castillo ibc(a)in.ilimit.es

According to the config, you do not even set the accounting flag for ACK, or I missed something there? Can you compile with memory debug turned on and test? Watch the syslog for critical errors. It can turn to be a buffer overflow somewhere. Once again, what is the version are you using?

Hey guys, I'm using kamailio-1.4.3-notls with ACC module on mysql.

[Kamailio-Users] Kamailio Newb questions
by carl Lougher 27 Feb '09

27 Feb '09

Howdy, I'm trying to remove the media/rtp streams from an asterisk server for natted users so would like to know if this is possible with kamailio. Qu's: What is the best option? rtpproxy/mediaproxy? nathelper? If i use kamailio to achieve this does it mean that i still have to carry the rtp streams through the kamailio server instead? Also will i need to change the logon info for the clients so they now logon to kamailio then i just point registrar to asterisk? Can i use kamailio for sip trunks to asterisk and carry rtp and natted clients media streams rather than register to asterisk? Many thanks, Taff..

[Kamailio-Users] default config file
by Elena-Ramona Modroiu 26 Feb '09

26 Feb '09

Hi, looking at the default config file, we deliver something pretty useless and very insecure. I propose to add to it several features so it becomes really usable: - mysql support - even some use radius for aaa, mysql is for sure used for usrloc. Those using other db drivers can just replace the module - auth against db and check auth username against from/to username to avoid spoofing - accounting - at least to syslog to store more than default data which gives nothing useful right now. Thinking to from/ruri username and domain at least in order to have caller and callee details - usrloc to database - nat traversal support with nathelper and rtpproxy - if rtpproxy is not running, will be just warnings at startup - the first part of the config will have some help of how to configure the environment to start the sip server (e.g., add user, ...) What do you think? Regards, Ramona

Dear Sir I am new to SER . So I want to know , is Opensips is Open source?. Does it need license?. What operating system needed to install the SER. Does SER support totally telephony, pc-pc , pc-phone, calling card , call back , IPPBX etc.. How many systems needed to install to work the complete solution. If possible , you can give me the installation and configuration ducumentation so that I can try to do the complete solution. Waiting for your reply.

[Serusers] Need easiest way to set/clear a flag and refer to it later in same call session
by Frank Durda IV 26 Feb '09

26 Feb '09

I need a simple way to set either a boolean flag (or integer value) during the INVITE of a given call in ser.cfg, and test that value via "if" elsehere in ser.cfg during the 183/200 response messages for that same call. This would be a data object unique to a given call, which should disappear/lose persistence/end scope when a given call ends. Not global, no need to write the value to disk, doesn't need to survive a restart of SER, etc. The various SER documents describe a number of things that could do this, but most seem overly complex, storing the object in a MYSQL database on disk or something, and these all seem so excessive. There also appear to be a few built-in flags, but the documentation suggests that all are actually there for specific uses and so use for other things might not work. I simply want to make a determination of something during the INVITE for call 12345, and be able to refer to that flag or integer value later on when the various response messages for the same call (#12345) are coming back through. I can't make the same determination on each message after the INVITE because the original src_ip address value where the INVITE came from doesn't seem to be in a testable variable when handling reply messages, or at least not in one that is clearly documented. I've chased a number of possible ways this might be done, but tire of being referred away from the doc that came with the source and over to web sites that tell me this or that module that might do part of what I need is deprecated and to use this other module, but the web site for the other module says that the first module is better suited to what I want to do (a circle), doesn't show how the set value can actually be tested, or the web page just doesn't work anymore. So, assuming there is a simple way to do this, I need a quick code snip showing how to set/clear/assign a value to such a beast within INVITE handling, and a quick code snip of how to test it in an "if" statement during 183/200/110 type response messages. Whatever it is, the value set, cleared or being tested in one call should not affect any other call. Thanks in advance!
