Re: [SR-Users] Forwarding Relaying of REGISTER Messages
by kellon＠sis-grenada.com 25 Nov '12

25 Nov '12

Hi All Alex responded to my question saying the following: "You can relay SIP messages of any type just the same way as you do with INVITEs -- e.g. t_relay(), forward(). But, proxying registration messages can have complications." can anyone give me some pointers or a list of some of these complications so that I can further research to see how its is done. I will attempt using the t_relay to view the issues, just need some idea more specifically what to look for! Thanks

Difficulties with with loose_route() when trying to handle non-compliant ACK
by Richard Brady 24 Nov '12

24 Nov '12

Hi guys I have a multihomed Kamailio proxy sitting between two B2BUAs on separate networks and record-routing all dialogs. The problem I have is that when one of these devices receives a 200 OK, it does not populate the RURI of the ACK correctly. Instead of taking it from the Contact header on the 200 OK, it uses the user part from the Contact header and sets the domain to the proxy IP. It then also populates the Route headers. The ACKs are below and the IPs are: 10.152.1.92:5060: UAC on … [View More]

Using uac_req_send function
by Freddy C 22 Nov '12

22 Nov '12

Hello, I'm using uac_req_send () to send a request generated in Kamailio (eg Example 1.21. UAC module) $ uac_req (method) = "OPTIONS"; $ uac_req (ruri) = "sip: kamailio.org"; $ uac_req (furi) = "sip: kamailio.org"; $ uac_req (turi) = "sip: kamailio.org"; uac_req_send (); However, I need to capture the responses of this request with failure_route TM module. Is there a way to capture these responses when I'm using uac_req_send() function? I appreciate your comments. Freddy

How does SIP transfer work?

22 Nov '12

Hello, I've been searching the internet to find an explanation on how SIP transfer works using Re-INVITE and/or UPDATE, but I can't seem to find a good source. >From what I understand(and this is the way we do it), the following happens: Bob=Caller Alice=Called John=Transfer party 1) Bob calls Alice. The usual INVITE,Trying,200 OK, ACK. 2) Alice transfers the call to John using Re-INVITE. a. Alice calls John. The usual INVITE,Trying,200 OK, ACK. b. Alice Re-INVITEs Bob … [View More]

Shared Call Appearances module
by Andrew Mortensen 21 Nov '12

21 Nov '12

I've been working on a Shared Call Appearances module for the past several months. It implements the Broadsoft SCA feature as laid out in Broadworks SIP Access Side Extensions Interface Specifications document. (Another implementation of the same feature was added to Freeswitch a few years ago, but we didn't want to use Freeswitch.) We've been testing and improving the module over the last month, and I think it's ready to share. The module is available at GitHub here: <https://github.com/… [View More]
