[OpenSER-Users] Wrong CSeq in NOTIFY after presence subscription refresh

by Michel de Boer

I perform the following scenario (openser v1.2.1): 1) Send a SUBCRIBE to openser for the presence event with expires = 3600 2) The subscription is established. Openser sends a NOTIFY with PIDF body. The sequence number in the CSeq header is 516. 3) 1 hour later I send an in-dialog SUBSCRIBE to extend the subscription for another hour. 4) openser sends a NOTIFY having sequence number 516 in the CSeq header. The sequence number of the NOTIFY should have been higher (517) as the sequence numbers of in-dialog messages should increase. I think this is a bug.

Re: [OpenSER-Users] The Via Header of CANCEL Message

by fancy

Hi Klaus: RFC 3665 page 54 line 4: A CANCEL constructed by a client MUST have only a single Via header field value matching the top Via value in the request being cancelled. and RFC 3665 at page 53: CANCEL is referred to as a "hop-by-hop" request, since it is responded to at each stateful proxy hop. and RFC 3665 at page 21: Client: A client is any network element that sends SIP requests and receives SIP responses. Clients may or may not interact directly with a human user. User agent clients and proxies are clients. So, for my opinion, the role of proxy in this case of RFC 3665 section 3.8 is a client when it sends CANCEL message to Bob. If I misunderstand any RFC meanings, please correct me. Thank you very much.

[OpenSER-Users] RE: SIP Trunking in openser

by Dan-Cristian Bogos

Hi Rizwan, there can be more ways of implementing your scenario. Here are two of most popular ones: 1. Using rewritehost("IP_OF_YOUR_PROVIDER") and then call t_relay() to send the request out. 2. Using directly t_relay("IP_OF_YOUR_PROVIDER") without rewriting the RURI host. The difference between the two approaches is that in the case of rewritehost() function u will alter the domain of RURI forcing it to be the ip address of your provider. In the second case, u will no longer alter the domain, but instruct t_relay() not to find the route by itself (no dns lookup or any other way) but send the request as it is to the IP which u specify specify. For more info, please consult the documentation of the two functions: http://openser.org/dokuwiki/doku.php/core-cookbook:1.2.x#rewritehost_sethost http://www.openser.org/docs/modules/1.2.x/tm.html#AEN345 Hope that helps, DanB On 7/4/07, Rizwan Hisham <rizwanhasham(a)gmail.com> wrote: > Hi all, > i tried to throw all my INVITE messages to an external IP address by using > the rewritehost function. but calls from my openser dont passthru. i need > to implement a sip trunk and throw my calls thru sip trunk to an external > ip. how should i do this?

[OpenSER-Users] RE: [Users] Interaction Presence Agent - Presence User Agent

by Schumann Sebastian

Dear Anca, Dear all After several trials I didn't come to a conclusion how to use the EXPIRES -1 with PUA_MI. All the time I enter this value to my FIFO file, the answer is pua_mi:mia_pua_publish: invalid expires parameter. This seems also logical to me, as source code of mi_func.c leads there on lines 97-102 (the expires is smaller than 0). Is there a support for PUA of the negative expires field, that is not implemented in PUA_MI? As I thought, PUA cannot be used standalone is there something I did not pay attention to? Any hints? Thanks!

You should just give the command with expires -1 and the pua module will refresh Publish until you give a command with expires 0. regards, Anca Schumann Sebastian wrote: > Dear all, > > > > I have a question for understanding: I have implemented one OpenSER as > Registrar and one OpenSER as Presence Agent plus XCAP Server 1.0.0. > This is all working so far with newest SVN Release (Big Thanks to > Ovidiu and Anca for the hint) of OpenSER. > > > > Now I want to deploy a Web-Front-End for user interaction with the > Presence Core, because not all clients used are SIMPLE capable.
