After installing Siremis as per the instructions, i get the following error. Anyone know how to solve this? "Not able to get the right data table of given form help.form.HelpWidgetListForm" After clicking OK I get this: "Unable to create object from class Openbiz.TableForm. TypeError: table is undefined" Every page click invokes this error.

Hello, I am trying to make an incoming PSTN call to and extension connected to Kamailio. I have set up the db_alias module and I have allowed the gateway to bypass the authentication. When I try and make a the call from the PSTN line I keep getting a 489 Bad Event error. Can someone let me know what the problem could be, thank you. My output is as follows: U 2013/07/14 21:15:59.265174 10.243.63.204:5060 -> 64.136.xxx.xxx:5060 SIP/2.0 403 Not (AJ Test 01) Allowed.

tls client to udp proxy

hi I have set up tls on kamailio successfully, but when I relay a TLS client to an other proxy ($ru = "sip:" + $rU + "@" + "127.0.0.1:5070;transport=udp";) via udp I get error messages. >From the timing it seems like this warning always appears after I get 200OK from proxy, the Invite gets sent correctly, but kamailio seems to fail while sending back the ACK. 18(11231) WARNING: <core> [forward.c:270]: WARNING: get_send_socket: protocol/port mismatch (forced udp:77.180.86.63:5060, to tls:127.0.0.1:5070) TCP->UDP works.

configuring an incoming PSTN line...
by arun Jayaprakash 13 Jul '13

13 Jul '13

Hello, can someone please give me some pointers as to how to configure the proxy server to receive incoming calls from a PSTN line. I had not problem setting up extensions and making outgoing PSTN calls. I am not able to find any documents ( or I am not looking in the right place ) as to how to configure the system to receive incoming PSTN calls. The DID number I have from my provider gives me the 10 digit DID number and the IP address of their server. Thank you for the help. Regards, Arun

question about rtpproxy "r" flag
by Juha Heinanen 13 Jul '13

13 Jul '13

rtpproxy_offer and answer functions have "r" flag described as follows: r - flags that IP address in SDP should be trusted. Without this flag, rtpproxy ignores address in the SDP and uses source address of the SIP message as media address which is passed to the RTP proxy. how does rtpproxy "use" this ip address? if sip message comes from behind nat, ip address in sdp is local address, not the address where rtp packets come from. and if this request has passed another (e.g. outbound) proxy before hitting the current one, also source address of sip message is not the address where rtp packets come from. either address thus seems to be useless for rtpproxy. -- juha

Asterisk cluster with Kamailio for load balancing.
by Володимир Іванець 13 Jul '13

13 Jul '13

Hello everyone! Recently I became interested in concept of putting couple of Asterisks servers in cluster. So I tried to replicate this scenario in testing environment. I was using database back-end for Asterisks settings and statistics and Kamailio as a load balancer. Obviously it did not worked [image: :cry:] . There is possible to make so many mistakes. Now I'm trying to find some step by step tutorial, but nothing yet. If someone experienced this, please advice. And if someone have useful links, please share. Thanks a lot.

Re: [SR-Users] Carrier Failoverand LCR
by Keith Hubner 12 Jul '13

12 Jul '13

Hi, Just a quick question, will the LCR module provide sufficient failover capacity? I have used the dispatcher module and like the way it marks a peer as down if it can't be contacted however I need to utilise the LCR functionality. Maybe a combination of the both will be best? Thanks, Keith

how to make dispatcher module use more than one tcp connections to the destinations?
by Allen Zhang 11 Jul '13

11 Jul '13

Hi list, I have a loadbalancer before sipproxies. I call t_reley() on the dispatcher to forward requests to destinations. All goes well under low load. But when load goes up to 500 requests/s, the loadbalancer still sends requests via only one tcp connection. This maxes out the tcp write queue. Of course I can increase the 'tcp_conn_wq_max' value but it doesn't solve the root problem. How do I make the loadbalancer start a new tcp connection to the destination when existing one becomes too busy? (Is it possible?) Regards, Allen

Best Practice for Routing Trusted Peers to PSTN
by Tony Turner 11 Jul '13

11 Jul '13

Hi I am fine with registered users sending and receiving calls from/to PSTN. Now I route registered users calls to/from PSTN fine Kamailailio<----->freeswitch<------------>IVR (PSTN) Best Practice for routing Trusted peers (inbound) to IVR/PSTN (SIP Trunking Service) Trusted peer1 -----> Kamailio -----> freeswitch ------------> IVR (PSTN) Where do I/ how do I route calls from trusted peers not to users but down to PSTN IVR? Say for example Trusted Peer 1 sends to my Kamailio IP sip:398998xxxx@xx.xx.xx.xx:5060 As I add a Trusted peer I would like to add a route and insert prefix for when it routes to freeswitch ---> Do I use carrier route or LCR etc, I want to be able to add trusted peers but add routes without editing the config file and restarting Kamailio. The reason I ask is I'd prefer to do it correct method at the start as it's a nightmare changing once I have lots of trusted peers. Thank you Tony Turner
