Re: [Serusers] SER proxy and SER+SEMS media server

by Samuel Osorio Calvo

You might try to just forward without modifying the Req-URI with the config file options: t_relay_to_udp(ip, port); OR t_relay_to_tcp(ip, port OR forward(ip,port); where the tuple ip,port corresponds to the SER instance acting as voicemail/conference server. The last option does not require the tm module and does not involve any transaction, Depending on your performance requirements, it should be better to use one or another... Hope it helps, Samuel. Unclassified. >>> Teemu Harju <teemu.harju(a)gmail.com> 09/16/05 03:11PM >>> Hi, I'm implementing following kind of system. I have two separate machines where I've installed SER on. The other machine has also SEMS installed. Like you probably already figured out other is used as a plain proxy/registrar and the other as a sort of UAS serving voicemail, conference etc with the help of SEMS. Now my question is, what is the best way to forward messages from proxy/registrar to the media server? I've done the forwarding according to the examples I've found and it uses rewritehostport() to forward messages to voicemail. Voicemail needs to get the email address from mysql database located in proxy. This is no problem connecting to the database, but isn't it so that when I've rewritten the Request-URI that the voicemail cannot find the email from database beacause it's rewritten and has the media servers host part in the URI. How have you guys implemented this? I would also need other SEMS plug-ins like conference, so I would also need to differentiate those requests also. Could I rewerite the Request-URI like voicemail@mediaserver? Can the voicemail still find out who was I actually trying to call to since the URI is rewritten? Is there difference in implementing the media server with asterisk? Wouldn't I need then two different databases? One in asterisk and one in SER. Thanks... -- Teemu Harju http://www.teemuharju.net

[Serusers] DTMF

by Iqbal

Hi I am guessing the ser does nothing with dtmf coming from the pstn side, since it's all in the rtp stream, if is there anyway of "seeing" what ser is doing with it, or what is being sent, I can see the dtmf in asterisk being passed from ser, but if I use another remote gateway, I wanted to be able to see if possible, even using ethreal or whatever Iqbal

[Serusers] Call forwarding Question (following issue 5)

by Aisling

Hi, I am testing the call forwarding features demonstrated in Issue 5 of the onsip getting started document. I found that blind call transfer worked perfectly but fwdbusy & fwdnoanswer gave me errors: ERROR: t_forward_nonack: non branched for forwarding ERROR: w_t_relay(failure mode): forwarding failed ERROR: sl_reply_error used: I'm terribly sorry, server error occurred. On the onsip site I noted that someone else had this problem and it was solved by putting append_branch in the fwdbusy and fwdnoanswer sections in the failure route. Thankfully that fixed those errors. However when I went to test fwdbusy again, it doesn't give any errors but still doesn't work. The call scenario was as follows: Windows Messenger client 3500 ring BT100 2092. 2092 is off the hook (thereby sending a 486 busy message) and the call should be forwarded to xlite client 5000. i.e. 3500 -> 2092(busy) -> 5000 The message sequence showed that everything was correct up to 2092 sending the 486 busy to SER and then SER sending an ACK back to 2092. But then SER sends a 407 proxy authentication required to 3500 which replies with an ACK....and that's it... Can someone explain why SER would send a 407 Proxy authentication to the original caller?...I thought this should only be in response to a register message?....

[Serusers] ser.cfg with PSTN gateway connectivity

by Alberto

Hi, I've read the SER Getting Started form http://www.onsip.org . When I configure the ser with PSTN Gateway (subject 8 of the guide) I can't register any client (403, Forbidden). I think, the problem is the next line of ser.cfg: if (!is_uri_host_local()) { if (is_from_local() || allow_trusted()) { route(4); route(1); } else { sl_send_reply("403","Forbidden"); }; break; }; I'd copied the permissions.allow and permissions.deny to /usr/local/etc/ser and in the .allow file I'd uncomment the last line (ALL:ALL) Any idea? Thanks. -- Alberto

Re: [Serusers] Distributing "OSP enable SER" binary file w/ source

Hi Jan, I am following up on the conversation that you and Vikrant had a short while ago. The OSP interface was implemented as a SER module. It does not require any changes to the core SER or any of its modules.

[Serusers] Making SER implement Jabber

by Saleh, Saleh

Hello Everyone, Can anyone tell me what I need to do next in order for SER version 0.9.3 to use the Jabber Module correctly? This is what I have done so far (on a Red Hat Linux 9 machine): Installed Jabberd 1.4.4 Installed GNU pth-2.0.4 Installed Expat 1.95.8 Installed Libidn ? I have Modified the config file for SER to load the Jabber.so module after the pa.so and tm.so (I'm sure this is where I am stuck, what to do with parameters in config file for SER) This is what I can/cannot do: I can run the jabber server I cannot run the SER with the config file which includes the Jabber.so module load command but I can run it without this command in the config file. I am using MySQL for SER What other files do I need to modify? What information do I need? I'm not very familiar with linux, I am a beginner... Any comments/suggestions/websites/help is GREATLY appreciated! Thanks, Saleh
