Connecting Two OpenSER machines

by SR-USER

Hi everyone. I have two machines running OpenSER, one machines runs OpenSER A and the other runs OpenSER B. Phone A registers in OpenSER A while Phone B registers in OpenSER B. I would like to allow Phone A call Phone B, but not the other way around. I am a newbie so sorry for my lack of knowledge. Would should be my configurations files for OpenSER A and B? Thanks in advanced

kamailio 3 and cpl - 483 too many hops

by Karl Harris

I am trying to incorporate a cpl script for testing purposes with kamailio 3 but have been met with failure with each try. Test scenario I have two sip phones registered to kamailio successfully (I can make phone calls between the two phones). The CPL XML is as follows: <?xml version="1.0" encoding="UTF-8"?> <cpl> <incoming > <location clear="yes" url="sip:1000@192.168.254.144<sip%3A1000(a)192.168.254.144>" > <log comment="cpl-log - just location" /> </location> </incoming> </cpl> This compiled successfully and is populating the cpl table in the openser database. When I call this from kamailio.cfg I get the 483 (Too many hops) error. If someone could spot an obvious error, I would appreciate it. The current kamailio.cfg file is as follows: ------------------ debug=8 log_stderror=yes memdbg=5 memlog=5 log_facility=LOG_LOCAL0 fork=yes children=4 /* uncomment the next line to disable TCP (default on) */ disable_tcp=yes /* uncomment the next line to disable the auto discovery of local aliases based on revers DNS on IPs (default on) */ auto_aliases=no port=5060 /* uncomment and configure the following line if you want Kamailio to bind on a specific interface/port/proto (default bind on all available) */ listen=udp:192.168.254.144:5060 ####### Custom Parameters ######### #

Match ip source of response into failure_route

by inge

Hi all, I try to do something like this on my failure_route[1] : if (t_check_status("503")) { if (ip_src==A.B.C.D) { ... } } The goal, is to prevent a 503 from a PSTN gateway and try another one for terminating the call. But, I realize that "src_ip" is the IP source of SIP Request. What could be a possible way to match IP source of the 503 responses ? Regards, Adrien L.

Fail to add user account

Hi All, Finally, the kamalio was installed on the Solaris 10 sparc and I can start it with the 'kamctl start', and it is running as showed below. However I cann't add user by using the kamctl, it always says the user already exists. And actually the susbciber table is still empty in mysql. Mysql is accessable with command "mysql -u openser -p ". What could be the issue? What are the log files I can check except the syslog?

domain name

by Anders

Hi, I have a carrier who insists and have configured their system so they can receive INVITEs to their domain name only, and not the IP. I cannot configure the gw for anything but IPs, but thought that I might be able to replace the IP address in the cfg. So I tried with setting $dd = "domain.com"; but that's not working, - I guess $dd is read-only or something. Any ideas? Thanks!! //Anders

Re: [SR-Users] 2 Asterisk servers re-inviting around kamailio even with t_relay being used?

See the > stock configuration file for more insight. Thanks Alex. I am testing this in the lab so I don't have a production config loaded, I am really focused on the carrierroute module and trying to figure that out so I'm running bare bones using the module example. I looked into the RR functions and read in the CR module that it invokes the TM when necessary so I was thinking it would take care of keeping track of dialogs. The thing that threw me off was the handling of the scenario 1 session with sipp was ok but with asterisk scenario 2 it was not. So I loaded in the record_route function in the main routing block and it did take care of the complete session with the asterisk server, so that problem is solved. What I am running into now is the failure route. If the initial session can not compete to the fist carrierroute, the call switches over to the failure-route[1] which invokes carrierroute again with another domain. Then the receiving asterisk server retransmits the initial OK 6 times, so the transaction is lost or not held in kamailio state, then the whole session drops after a few more seconds. I think there is something going on with the append_branch function that is throwing me off. It is needed so the failure route completes but it's not handling the complete dialog or I could be totally off. Thanks. JR -- JR Richardson Engineering for the Masses

Kamailio 3.0.1 and NAT

by Information

hi, I have configured kamailio 3.0.1 on fedora 12 and its working fine for ips on the network. But I am unable to get a working configuration for a natted client. If one client is natted and other is not, both can call each other through the kamailio server but only the natted client sends voice to the un-natted client while on tcpdump i found that the un-natted client is actually seeing the private ip of the natted client and trying to deliver packets there. So no sound reaches the natted client from the un-natted client. I have been searching for some days for some help in this regard but have not found anything i can use. help, regards. ***********************Confidentiality Notice*************************** The information contained in this electronic message and any attachments to this message are intended for the exclusive use of the addressee(s) and may contain confidential or privileged information.
