[Users] Checking received contact against location table
by Dimo 13 Oct '06

13 Oct '06

Hi, I want to tweak my openser setup so it allows calls (INVITES) only from registered contacts. I was wondering if there is a way to check the received contact in the invite message against the location table in mysql database, where i store the registered users. I do not want to make additional digest authorization of the Invites. I see that the registered() function in registrar module has something like that, but it makes the check on the request uri, not the contact. Also if someone can think of a better way to allow calls only from registered contacts I would greatly appreciate any tips. Thanks. Best, D.

[Serusers] ACK not loose_routed
by Cesc 12 Oct '06

12 Oct '06

Hello everyone! I have my system based on ser 0.9.6. Internal calls work just fine. I am now trying to interop with another system. It has a sort of asterisk functionality, but it is not asterisk, it is a private software company product. my.phone ---------> my.ser.proxy -------------> external.proxy -------------> external phone 10.111.0.119 10.111.0.50 10.111.0.20 10.111.0.144 There is no firewall or nat in the way. The problem, i think, is that the external.proxy is buggy. I told that to the company, but who knows when they will fix this. * Look at the OK (message #9 and #10). My.ser.proxy record-routes all invites. The Record-route headers reach the external.phone, which copies them in the OK message, sends the OK to the external.proxy ... and when this forwards it to my.ser.proxy, they are gone! The OK reaches my.phone, but then it generates my problem: the ACK. It contains NO ROUTE headers and the r-uri is also simply pointing to the external.proxy. If the ACK had the ROUTE headers, my.ser.proxy would loose_route the message and voila! But as loose_route() returns false, my (maybe bad) config file gets confused and treats it like a "new" call ... so it lookup("location") of the ACK r-ruri fails, and the ACK is dropped. Should i modify the config file so that ACK, if not loose_route'd, are simply t_relay'd? * They also modify the contact field. The reason is because behind the external.proxy could be H323 or SIP phones, so they sort of want to be a termination as far as signalling is concerned. I attach the message flow, hope it helps ... Thanks! Cesc

Re: [Serusers] How to see Active Calls
by Jiri Kuthan 12 Oct '06

account the calls and check the database for INVITEs for which there is no BYE. That's all. -jiri At 07:39 12/10/2006, ram wrote: >Hi all > >iam using old SER 0.8.12 with mysql > >how can check the , how many calls are active. > >Ram >_______________________________________________ >Serusers mailing list >Serusers(a)lists.iptel.org >http://lists.iptel.org/mailman/listinfo/serusers -- Jiri Kuthan http://iptel.org/~jiri/

[Serusers] Need help finding workaround for PRACK method
by Tomas Grinevičius 12 Oct '06

12 Oct '06

Hi, I have problem with PRACK support on my equipment. Central Switch requires support of PRACK method and some CPE does not support it properly… Could someone advice me if SER would be capable of "terminating" PRACK requests between softswich? SER should only transparently process all request, send PRACK request for soft-switch and modify fields that PRACK should not be triggered in CPE devices. Please help!!! Thank you very much in advance. /Tomas

[Users] Openser as an application level gateway
by Lindsey Hans Joseph Lao 12 Oct '06

12 Oct '06

Hello, Is it possible to configure Openser as an application level gateway? I am trying to setup a proxy server with Openser running on it and configured to change the contact header fields of the sip message from a private address to a public one. In line with this setup, the sip message is then forwarded to a registrar server. I tried using the mediaproxy setup on the ser getting started document but the registered contact address still pertains the private one. Can someone help me on this? Thanks!

[Users] acc_radius question
by Cseke Tamas 12 Oct '06

12 Oct '06

Hi, When sends openser accounting packets for INVITE, and BYE message? it seems to be, when received 200 OK. 1)for INVITE i need radius packet immediately, not just when it was answered. 2)for BYE i need accounting packet, when any error occured too. modparam("acc", "radius_flag", 2) modparam("acc", "radius_missed_flag", 3) this attribute mean that, should sent radius packet, when any error occured too, isn't it? However openser don't send accounting packet in this case. i run into the following error: ########## T called -> openser BYE sip:21.16.8.92:5060 ## T openser->called SIP/2.0 477 Unfortunately error on sending to next hop occurred (477/TM) ########## T caller->openser BYE sip:66610038641368254@21.16.8.90:5060; ##### # openser -> caller SIP/2.0 481 Call Leg/Transaction Does Not Exist.. So no 200 OK for BYE received, therefore no accounting packet to radius sent. How can i solve these problems? Btw, what could cause this 477 error? Thanks, Tamas
