Hi,i'm new to SIP. I want to integrate my existing Instant Messenger to SIP server. I mean i have to write some thing so that our IM users can chat with the other users using SIP. But i don't know SIP. Now i'm going through SIP docs. I'm getting the architecture, but i'm unable to understand what to write for the above problem. Whether we need to write one SIP enabled server or we have to use third party server. So please let me know what actually i need to do to get out from this problem. I'll be very thankful to you if you show me a path. thanks in advance. cheersg.sreedhar reddy --------------------------------- Do you Yahoo!? Yahoo!

Re: [Serusers] Routing subsequent SIP traffic through the proxy

by jaime.gill＠orange.co.uk

Hello Jiri, Of course, I meant the non-paranoic meaning, that is forcing the subsequent requests to go through the proxy. The question is related to the FCP module I'm trying to complete. In order to close the previously opened ports, the module needs to see BYE and CANCEL messages. When adding record-routing header from a natted proxy, this address must be changed to a public one whenever the message is for the public Internet. Is my understanding correct? My other concern with Record Routing is whether this translation for the request involves translating the RR field back to the one of the natted proxy, when the response hits the proxy. Regards, Jaime Jiri Kuthan <jiri(a)iptel.org> on 21/03/2003 17:28:48 To: Jaime GILL/EN/HTLUK@HTLUK serusers(a)lists.iptel.org cc: Subject: Re: [Serusers] Routing all SIP traffic through the proxy At 12:29 PM 3/21/2003, jaime.gill(a)orange.co.uk wrote: >Hi, > >Not sure if someone has asked this before.

In a paranoid understanding, that would include interception of iptel.org messages by someone else. In general, there are two options: setting an outbound proxy in phones and forcing subsequent requests hit a proxy through rr-ing. -Jiri ******************************************************************************* Important.

[Serusers] Authentication question

by Nimal Ratnayake

Hi, I want all users who have accounts on host A to have access to ser which runs on host B, (without having to add them again to the mysql database on host B.) I learned that Radius Digest Authentication cannot be used because it needs the Radius server to know the cleartext password of the user. Is there any other method that I can use in this situation? Nimal R.

[Serusers] auth_radius module problem

Hi, I have built ser and modules from the tar.gz file available on CVS. Authentication using auth_db works fine, but auth_radius results in a segmentation fault when I try to register.

[Serusers] New save_noreply() function for the registrar module

by Maxim Sobolev

Folks, We found that in some cases it is necessary to have a function which will save contact without sending reply to the UA. For example, it is useful when there is a need to do stateless forwarding of the REGISTER request, but at the same time save it in the local registration database (sending reply in this case will disable any retransmissions that might be necessary to ensure that the request actually reached the destination). Attached patch provides necessary functionality, it would be nice to have it included into the next release. Thanks! -Maxim

[Serusers] Multiple Registrations

by Ricardo Villa

Hi, When we have a situation in which a PC changes IP addresses (like on dialup), we end up with multiple registrations (see below). Is it possible to configure SER so that it only has the latest registration? [root@maui ser]# serctl ul show rvilla <sip:rvilla@200.58.193.72:5060;transport=udp>;q=0.00;expires=2773 <sip:rvilla@200.58.203.236:5060;transport=udp>;q=0.00;expires=3194 <sip:rvilla@200.58.203.61:5060;transport=udp>;q=0.00;expires=3544 On a related note, the registrar README says: "Name: lookup Params: table - Name of table that should be used for the lookup Desc: The functions extracts username from Request-URI and tries to find all contacts for the username in usrloc. If there are no such contacts, -1 will be returned. If there are such contacts, Request-URI will be overwritten with the contact that has the highest q value and optionally the rest will be appended to the message (depending on append_branches parameter value)." ....but as you can see all 3 contacts have the same "q value" (whatever that stands for). How does one resolve such an issue? Thanks, Ricardo
