[Serusers] Call Forward Redirection By server(SER)

by Cyprian Clement

Hello Community, I have managed to setup my SER to do serial forking(CFU) by simply intercepting the incoming INVITE and generating a new INVITE to a user that is different from the one contained in the original invite. This means the user ID of the Request URI generated by the SER is different from that of the original/received RURI. I am currently working on the Call Forward (CFU, CFB, CFNA) scenarios. I would like to configure the SER in such a way that it generates the 302 message back to the caller and this 302 contains the contact of the third party that the caller needs to get in touch with. Basically, the caller should generate a new INVITE to this third party since the intended target has had his phone activated with the CF feature. I currently managed to get the SER do the serial forking(i.e. without sending back the 302) using the AVPops madule as instructed in the User Guide. Does the AVPops do the redirection too? if yes, then I will really appreciate to hear your helping info on how to achieve this. Many thanks in advance. Cyp. --------PS: if anything is unclear I can clarify. ___________________________________________________________ Yahoo! Answers - Got a question? Someone out there knows the answer.

Re: [Users] failure_route problem

by Klaus Darilion

openser uses syslog logging. The destination of the logs is distribution dependent. E.g. debian based -->/var/log/syslog, redhat based --> /var/log/messages. Read http://openser.org/dokuwiki/doku.php/tutorials:debug-syslog-messages for details about to configure logging. regards klaus ps: please cc the list Yago Bargalló wrote: > Sorry, but I've tried to use xlog but I don't know where logs are printed.

Re: [Serusers] Frustrating error - please help

Samuel, That was very helpful. The last line of the output made me wonder what was happening with the "ESTABLISHED" link. It was CounterPath Eyebeam UA that needed to be restarted.

[Users] question about the openserctl ping command

by Papadopoulos Georgios

Hello all, I am using the openserct ping command to periodically check whether openser is working properly (If there is a better way to do this, please let me know). My script looks like this: SIP_URI="sip:213.5.xxx.xxx:5060" OPENSER_DIR=/root/openser TMP_FILE=/tmp/openser_ping.result $OPENSER_DIR/bin/openserctl ping $SIP_URI > $TMP_FILE 2>&1 Sometimes in TMP_FILE I see the following type of message: mkfifo: cannot create fifo `/tmp/openser_receiver_26907': File exists anaconda-ks.cfg install.log install.log.syslog mbox openser ERROR: error opening read fifo /tmp/openser_receiver_26907 At the same time openser seems to be working fine, however because the script gets this error, it restarts the server (the idea is that if ping fails then restart). Any idea why this is happening? What is the best way to make sure openser is working properly? I am assuming that a succesful ping only proves that one child is working properly.
