by Rizwan Hisham 04 Jul '07

04 Jul '07

Hi all, I am a new user or openser. It is difficult for me to decide which release should i install on my computer as i have no knowledge of why there are so many branches of openser production. for startup, i have installed openser version 0.9.5. but i need to know whats the difference between 0.9.x 1.0.x 1.1.x and 1.2.x? -- Best Regards Rizwan Hisham Software Engineer AXVOICE Inc. www.axvoice.com

Re: [OpenSER-Users] The Via Header of CANCEL Message
by fancy 04 Jul '07

Hi Bogdan: I did not use forward(), but I load sl module. And I did use sl_send_reply() to reply 483 and 513 message and sl_reply_error(). The attached file is my openser config file. I use this config file to run openser. The under RFC3665 section 3.8 condition, I got two Via headers as I mentioned before. So, according to my config file, Openser is a stateless proxy server under RFC3665 section 3.8's condition? Thank you.

Hi Bogdan: RFC3665 didn't mention any stateful or stateless within all the document. So I think it is just not covering it. By the way, is openser a stateless proxy server? I think it is a stateful proxy server! Can I config it to be a pure stateless or stateful proxy server? Thank you.

Re: [Serusers] How SER communicate to other SIP server
by roayu 04 Jul '07

04 Jul '07

Hi, Olaf! >From what I understand about forward() is that it will forward the request to the given destination statelessly. Whereas for t_relay(), it will relay a message to the destination stated in current URI statefully. How do I get the URI to point to the other SIP server by using t_relay() as I couldn't assign any IP address for t_relay(). I managed to assign an IP address by using forward(). I tried to use both. Unfortunately, I still failed to forward the message to the another SIP server to establish the call. Is there any functions I need to use before using either those 2 functions? FYI, I will only call them when it starts to INVITE. Thanks!

Yes, several. First of all, rewritehostport() does no forwarding, it just changes the domain part of the request URI (not To). Use forward() or t_relay() depending on your particular needs.

[Serusers] User update on SER
by Felipe Louback 03 Jul '07

03 Jul '07

Hey, How does SER updates a user location? For exemple, upon the first REGISTER message, it keeps the location of the user in a database or so. But this entry has a expire time. How is this expire time updated? SER updates it upon receiving another SIP REGISTER or OPTIONS messages? I know that this update is done, but I am quite confusing about how it is done.
