[Kamailio-Users] How to change request uri with Header value?
by Ramu 02 Mar '09

02 Mar '09

Hi All, I have situation where I need to change the request uri with To header value. Scenario: OpenServ will receive INVITE as follows INVITE sip:2000@open-ser-ip SIP/2.0. To: "2000"<sip:2000@sip.mydomain.com <sip%3A2000(a)sip.mydomain.com>>. Now I would like to change the request uri as follows: INVITE sip:2000@sip.mydomain.com <sip%3A2000(a)sip.mydomain.com> SIP/2.0. To: "2000"<sip:2000@sip.mydomain.com <sip%3A2000(a)sip.mydomain.com>>. and will do a lookup location. Ramu

[Serusers] fix_nated_contact onreply
by samuel 02 Mar '09

02 Mar '09

I have seen lots of default config files where in the reply route only after checking the message (client_nat_test(1)) fix_nated is called. Why is not called when the NAT flag is set upong lookup_XX? In ser-oob I think the reply_route should include the case of a user called behind a NAT and the reply is not fixed due to some router in the middle. Will it hurt including fix_nated_contact in the case of checking the flag? Friday thoughts... Samuel

Re: [Kamailio-Users] how to know if my gw servers are active ?
by BERGANZ François 02 Mar '09

02 Mar '09

For the database, asterisk and SER work on the sameone. in sip.conf create one for SER and insecure=invite. It accept all from SER In the SER, configure the auth_db module to check the username col and password col. SER is a wall between client and asterisk(s). The same SER can be a wall between asterisk and provider. It is just a gymnastic! To test, it, the best is to have all in the same UC. And have one virtual networkInterface per Asterisk and SER.

Abdul Hakeem, I use Asterisk-SER for another way. SER authenticate users and asterisk(s) accept all SIP frames from the SER. >>How did you create the users databases on Asterisk and Ser ? Also, how did you configure Asterisk to forward registration requests to Ser ? If you could send me sample Asterisk/Ser configuration, I'll be much grateful. Then, asterisk(s) forward the call to the provider. When a call come from the provider, asterisk forward it to the SER and the SER just do a lookup(location)! >>What happens if a call comes in to SER directly, & it has to do a quick lookup to see which Asterisk the user is currently located ? The reason I ask is because for example User-A with e164 number/DID +447931800952 might be registered to Asterisk-X now and 10 minutes later register with Asterisk-Y, Did you implement some refresh mechanism on the SER database ?. Because in this case inbound IP calls are hitting SER first before being redirected to the appropriate Asterisk server. I look forward to your reply.

Hello, How did you setup your Asterisk to update SER/OpenSER/Kamalito's database ? I am trying to setup a solution for 2 Asterisk or more servers to allow dynamic and not static user registration. i.e. any user can register with any of the Asterisk servers. Let's say if UserA register with Asterisk1, this will reflect on SER's database where to route the call. In this scenario of UserA now register with Asterisk4 5 minutes later, SER's database will be automatically updated and calls to UserA will be automatically routed to Asterisk4. What I am hoping to achieve is not to do this via manual intervention. Any this will be much appreciated.

[Kamailio-Users] how to know if my gw servers are active ?
by BERGANZ François 02 Mar '09

02 Mar '09

hello, I have a list of servers in my database. I need that openser send OPTIONS to servers. for example, I could have a col 'active' to know if each server is active or not. In fact, I need to do an other style of dispatch, and, I cant use the dispatcher module! is there a solution for that ?
