This is, if Alice starts a MSRP messaging session with Bob, would Carol see both Alice and Bob with activity On the phone? :) Hi Inaki, Yes, it will. In fact what happens is that the dialog module will trigger the pua_dialoginfo callback for created dialog and pua_dialoginfo will generate a Publish with state trying. The dialoginfo - presence translation feature in presence module will then generate a presence publish with substatus ringing. The pua_dialoginfo doesn't do any check of the SIP message and assumes that if the dialoginfo_set function has been called from the script, then it should generated dialog publications for that dialog.The problem is that the MSRP offers are also carried in SDP bodies so it is hard to check this from the script and not call dialoginfo_set for those Invites. I think that somewhere in this path a check should be added to prevent generating dialog info and presence publications for MSRP Invites. Probably either by writing a function to be called from script like is_msrp() or doing the check in pua_dialoginfo.

Hi Inaki, The mixing is done as until now, no changes in this part. The presence info extracted from dialog is considered to have the greatest priority and is inserted the first.

[OpenSIPS-Users] New features in BLF and presence
Hi all, Recently OpenSIPS had two important improvements in BLF (dialog info) and presence. The first one gives more flexibility and makes it adaptable to more platform architectures. The second one transforms dialog information into presence, mixing the two and making the presence server more powerful as it will be able to notify the watchers not only about the state that it received in Publish messages but also if the user is currently in a call. First, BLF was given more configuration options. Until now, if you wanted dialog info support you had to call a function ( dialoginfo_set ) on an initial INVITE and the server would have generated Publish messages for dialog event for every new event in that call ( ringing, established, terminated, etc. ) for both the caller and callee and using the URI's in From and To header. This fixed behavior is not sufficient in many cases. The first problem was with the fact that it generated publications for both the caller or callee if the domain was considered to be local. In some cases it can be obvious that the server should not generate dialog info for a party. For example, if you determine that the caller or callee is a PSTN number, then there is no reason the generate dialog info for it. And this deductions and decisions can only be made from the scrips so it is normal to be able to control from the script for which party the server should generate dialog Publications. To enable this, we allowed dialoginfo_set function to receive a parameter through which the script writer can tell for which of the call parties it wants dialog publications. (http://www.opensips.org/html/docs/modules/devel/pua_dialoginfo.html#id227160) The second problem was with the URIs used as presentity URI when generating the Publish messages. In most cases the real callee URI is obtained in RURI after a series of transformations done in the script. Therefore, we changed the default source for the callee URI to the RURI ( until now it was the URI in From header). The RURI to be used is the one found in the message at the time when dialoginfo_set function is called. More than this, we allowed for the two URI's caller and callee to be set to custom values by completing some pseudo variables. The specs for these pseudovariables must be specified in two module parameters. If a pseudovariable is set at the moment when dialoginfo_set function is called, its content is used as presentity uri, otherwise the default values are used ( RURI for caller and To uri for callee). These two improvements make BLF adaptable to any needs. The second important feature is the possibility to mix dialog information with presence. Until now, dialog and presence were two different things. If you wanted to know if someone is currently in a call, your phone had to support BLF and send Subscribes for dialog event. Knowing if someone is in a call is quite a demanded feature. The simplest example is with the assistant manager that first answer the calls and needs to know if the manager line is idle and she can transfer the call to him. The reality is that few phones have support for dialog event notifications, but more have support for presence. Therefore, we decided to mix the dialog information with presence at the presence server. Now, the presence server is able to tell you if a buddy is in a call through presence Notifications even if his phone did not send a presence Publish with this information. The mixing in fact generates presence from dialog info when a call is in progress and mixes this with the presence information received from his phone through Publish. The result is that when a buddy is in a call you will see a status indicating this and in the rest of the time you will see the presence state that the buddy set in his client. This behavior is enabled by setting a module parameter (http://www.opensips.org/html/docs/modules/devel/presence.html#id228554). This is a very nice feature that gives more power to the presence server making it able to satisfy the needs of the end users even if their phones are less capable. Hope you will find these features useful. Regards, -- Anca Vamanu www.voice-system.ro ___ Users mailing list Users@lists.opensips.org http://lists.opensips.org/cgi-bin/mailman/listinfo/users
Re: [OpenSIPS-Users] New features in BLF and presence
Anca, This sounds like a very good start. My experience is that this is something that different people will want to use in different ways. Some people don't want phone calls to affect presence, where others say differently In the future, there might be need for a per-uri configuration option or something like that.
