Hi, I have a kamailio 3.1.4 installation installed from the APT repository kamailio.org. I have read about a python script route_graph which I would like to test. The only thing is, i cannot seem to find out what deb package I should install to have this. Could someone point me in the right direction please? :) Best regards Stefaan

Hi all, I would like to know how kamailio sends Notify request by using the handle_subscribe of presence module. My purpose is to modify the request to add information for "message waiting indication" like : Messages-Waiting: yes, Voice-Message: 2/0 (0/0), ... I need your help ! Thanks in advance, Best regards Marvin -- View this message in context: http://old.nabble.com/MWI-Notify-Request-tp31954500p31954500.html Sent from the OpenSER Users Mailing List mailing list archive at Nabble.com.

Internet RTP filters
by Dominguez Jover, Ricardo 30 Jun '11

30 Jun '11

Hi everybody, First to say sorry if this is not the right list to send this post, anyway we hope somebody can help us. We have Kamalio 3.1.3 working since many time ago. We use an RTP Proxy for NAT issues in the server side and STUN for NAT issues in the internet client side. Calls in Spain are working fine. This month one of our users has gone to Rwanda (our University has created a Hospital and a School in a region called Nemba). They are using an internet connection by satellite, with a low bandwith (128kb down, 16 up). In some countries we have trouble with internet calls. SIP signaling works fine, the call rings and is stablished, but there is a problem with RTP streams: - RTP streams sent by RTP proxy to client in internet never arrives to the client in the internet (although they RTP is sent to the right IP and port) - RTP streams sent by client in the internet never arrives to RTP proxy (although RTP is sent to the right IP and port) As I said this happens sometimes, and it's happening in Rwanda. We usually solve this problem making a VPN connection to the University, then the RTP stream works fine. However when our Rwanda's users connect to VPN, the Bandwith goes down (45 kbps down and 8kbps up), so they can hear as perfectly, but we can't hear them. Does anyone know if T companies are filtering RTP traffic? I've tried to change ports in RPT Proxy with no result. How could we solve this? Thanks in advance and best regards, Ricardo Dominguez Universidad Miguel Hernández de Elche

Re: [SR-Users] MWI handling

If you are using asterisk as a voicemail server, let asterisk to handle the SUBSCRIBE and don't involve the kamailio presence server in this process. If you really want to use kamailio as a mwi presence server, then you will need to build some external scripts for pooling the asterisk mwi db and send PUBLISH out. I would stick with asterisk handling the mwi subscription and configure kamailio as a relay only for those events.

Re: [SR-Users] MWI handling

I've done that in this fashion: Kamailio is only proxing SUBSCRIBEs to Asterisk and it's replying with NOTIFYs to Kamailio, Kamailio is just proxying reply to UAC. So Kamailio is transparent for MWI. But it looks like spike. I'd better send PUBLISHes from Asterisk to Kamailio for all the clients and Kamailio reply with NOTIFY to subscribed ones. This is like Kamailio MWI module was designed. Anyway, thanks for the help. Scripts for making PUBLISHES is spike even more.

This makes the main problem as in documents I've found on asterisk is that it doesn't support PUBLISH, i.e. there is no way to force sending them on MWI event. It works only on SUBSCRIBE-NOTIFY scheme. Did you succeeded with PUBLISH on Asterisk in order to inform Kamailio about MWI? If yes, how? Cause right now, for me, it looks like a theory, cause no mechanics to force asterisk send PUBLISHes. Thank you.

mq_fetch and while loops
by Watkins, Bradley 30 Jun '11

30 Jun '11

I'm having an issue trying to use the construct show in the module documentation. The docs show: while(mq_fetch("myq")) { xlog("$mqk(myq) - $mqv(myq)\n"); } And I'm doing essentially the same thing (differently named mqueue, but otherwise identical), but invariably I get this in the logs: ERROR: <core> [action.c:1388]: ERROR: runaway while (559, 28): more then 100 loops Am I doing something wrong, or is mq_fetch not returning appropriate values for successful versus failed fetches? This is on Kamailio 3.1.4, FWIW. Regards, - Brad The contents of this e-mail are intended for the named addressee only. It contains information that may be confidential.
