[Serusers] help required disabling DNS lookup
by geethanjali.csg＠wipro.com 01 Apr '08

01 Apr '08

Hi, I am trying to set up calls between 2 domains without using DNS lookup. UA -> domain1 -> domain2 -> UA I am using static forwarding route the all requests. Requests should be routed using this forward logic only. Both DNS lookup and forward logic are happening. Since I have not configured the DNS, an error "Unresolvable Destination" is seen by the UA. Ser log displays errors related to DNS lookup. I don't want the DNS lookup to happen. Requests should be routed using the forward logic only. Can someone help me solve this problem.

[OpenSER-Users] [openser 1.3] loading module auth.so stop my server
by Pascal Maugeri 01 Apr '08

01 Apr '08

Hi I'm still unable to have a working server 1.3 that loads the module auth.so. It is weird because there is no error message in my log file also I set the debug level to maximum. But after starting the openser service, it says it is successful but there is no running process (pgrep openser does not show anything, when it does if I remove the load auth.so)! How can I get more debugging info about the loading and initialization of auth ? Can anybody share with me his or her configuration file ? I may miss something in mine: loadmodule "sl.so" [...] loadmodule "auth.so" (I believe it is sufficient). Is there any known issue using Redhat Enterprise 4 ? Regards, Pascal

[OpenSER-Users] Problem in finding invite tsxn for ACK.
by Vikas CG. 01 Apr '08

01 Apr '08

Hi All, We were using the openser server as reg/proxy to test sip gateway. We observed that if we run openser in TCP mode it will add 2 record-routes one for TCP and UDP. But when we put hold UA-client i.e. when we send reinvite the openser server is adding only one record-routes But in ACK for reinvite it is adding 2 record-routes. I am also attaching the sip flow. It would be grateful if any body tells us is this behavior is correct? Because we are depending on record route to find the invite tsxn for ack. Thanks, Vikas C.G.

Re: [OpenSER-Users] PUA/PUA_MI: More than one Publish sent
by Schumann Sebastian 01 Apr '08

01 Apr '08

Sorry, one short mistake: Of course, after last expire, the expires only removed the a.1207041424.4027.8.0, which was the last one published. The a.1207041424.4027.7.0 from the same publication remains in the table. It has nothing to do with odd and even numbers. Regards Sebastian -----Original Message----- From: Schumann Sebastian Sent: Tuesday, 01. April 2008 10:32 AM To: 'Anca Vamanu' Cc: users(a)lists.openser.org Subject: RE: [OpenSER-Users] PUA/PUA_MI: More than one Publish sent Dear Anca Thank you for the response. The publication of more than one message in your described scenario I understand. In my case, immediately after the first PUBLISH is sent, a second one is sent afterwards. OpenSER does not use the most recent etag for an update, but creates a new one, that is never been removed automatically. If I send an expires=0 message after the publication, only the first published etag is removed. Here my publication script: #!/bin/bash # FIFO command to PUBLISH hard-presence state of user via PUA # #config values OP_SYSUSER="alice(a)10.96.115.129" OP_SIPURI="sip:$OP_SYSUSER" OP_STATE="open" OP_EXPIRES="-1" #build reply fifo file rm -f /tmp/openser_fifo_reply mkfifo /tmp/openser_fifo_reply cat /tmp/openser_fifo_reply& cat >/tmp/openser_fifo <<EOF :pua_publish:openser_fifo_reply $OP_SIPURI $OP_EXPIRES presence application/pidf+xml . <?xml version='1.0' encoding='UTF-8'?><presence xmlns='urn:ietf:params:xml:ns:pidf' xmlns:dm='urn:ietf:params:xml:ns:pidf:data-model' xmlns:rpid='urn:ietf:params:x ml:ns:pidf:rpid' xmlns:c='urn:ietf:params:xml:ns:pidf:cipid' ntity='$OP_SIPURI'><tuple id='gigpoej8'><status><basic>$OP_STATE</basic></status><rpid:user-input> Har d-State</rpid:user-input></tuple><dm:person id='0jfqoiet'><rpid:activities><rpid:unknown/></rpid:activities><dm:note >Hard-State</dm:note></dm:person></presence> EOF And my expires script: #!/bin/bash # FIFO command to PUBLISH hard-presence state of user via PUA # #config values OP_SYSUSER="alice(a)10.96.115.129" OP_SIPURI="sip:$OP_SYSUSER" OP_STATE="closed" OP_EXPIRES="0" #build reply fifo file rm -f /tmp/openser_fifo_reply mkfifo /tmp/openser_fifo_reply cat /tmp/openser_fifo_reply& cat >/tmp/openser_fifo <<EOF :pua_publish:openser_fifo_reply $OP_SIPURI $OP_EXPIRES presence application/pidf+xml . <?xml version='1.0' encoding='UTF-8'?><presence xmlns='urn:ietf:params:xml:ns:pidf' xmlns:dm='urn:ietf:params:xml:ns:pidf:data-model' xmlns:rpid='urn:ietf:params:x ml:ns:pidf:rpid' xmlns:c='urn:ietf:params:xml:ns:pidf:cipid' ntity='$OP_SIPURI'><tuple id='giqpoej8'><status><basic>$OP_STATE</basic></status><rpid:user-input> Har d-State</rpid:user-input></tuple><dm:person id='0jfqoiet'><rpid:activities><rpid:unknown/></rpid:activities><dm:note > ard-State</dm:note></dm:person></presence> EOF I start first publish, then expire, then publish again and so on. The following etags are created normally: e.g. a.1207041424.4027.1.0 a.1207041424.4027.3.0 a.1207041424.4027.5.0 At some point, another one is created together with the "normal" one, e.g. a.1207041424.4027.7.0 and a.1207041424.4027.8.0 The expires only removed the a.1207041424.4027.7.0 (all odd numbers). The published one with the even number stays forever. I don't know what can be the reason. Here my OpenSER configuration file extract from pua module: modparam("pua", "db_url", "mysql://openser:openserrw@localhost/openser") modparam("pua", "db_table", "pua") modparam("pua", "update_period", 10) modparam("pua", "default_expires", 600) Thanks for help.

March 2008 3:05 PM To: Schumann Sebastian Cc: users(a)lists.openser.org Subject: Re: [OpenSER-Users] PUA/PUA_MI: More than one Publish sent Hello Sebastian, Indeed sometimes more that one Publish messages are sent. I will explain when and why. It is possible for someone to request through the MI command to publish a state that should be active for 5000 seconds (you probably know that -1 in expires filed means infinite time). But the max expires in presence server is lets say 3600 sec. If no other publish request is received before the first one expires, the record is deleted. So, to respect the requested time, the pua module generates itself another publish when the first one is close to expire just to update the validity time. Now, if for a subsequent mi command you do not sent the etag parameter ( set it to '.' value), the most recent etag will be found in pua module, and a correct Publish message will be sent. I have just now tried the scenario you described and it works perfectly for me. So, I want to ask you to say exactly what you are doing because there must be something you have missed out. Is the presentity uri exactly the same for the first and the subsequent mi requests? After how much time have you sent the mi request that fails?

Re: [OpenSER-Users] dialog matching criteria
by Jayesh Nambiar 01 Apr '08

Hi Bogdan, Thanks for your reply. I tried of acheiving the same as follows: Enabled DB support for dialog module. If the called number is 123456, I first query the dialog table to retreive the count on to_uri and compare it with a certain limit value. If the count is equal to or greater than the limit value, just reply as 403, Forbidden. I am about to finish this today and will let you know the results. I just wanted an expert advice on if the logic is ok and efficient. Also there is a column in the dialog table which is caller_route_set and callee_route_set, can someone please tell me from where these values are retreived from as it stays blank while checking the dlg_list. Also is it possible to insert some custom value in this column to implement any further logic.
