Hi! It looks like there is some restriction of the IP address allowed to signIn to mediaproxy. Can this be configured or is this hardcoded? thanks klaus

[Serusers] Carrier-grade framework for SER
by Andreas Granig 27 Sep '06

27 Sep '06

Hi guys, I'd like to propose another possibility for a highly-available and scalable system design based on SER: The problems I've encountered for scalable systems are: - Distribution of the user location and alias location among the nodes (user location is based on registrations, alias location comes from web interfaces and is used for call forwarding). - Reloading up to date location tables after breakdown and recovery of a node So I'm just thinking loud about the following provisioning system: - Write a client which fulfills the this demands: - Receive one or more locations from SER via a SER module or from a web application and distribute them to other known clients. Take care of retransmissions if a client isn't reachable or reports a temporary failure. - Receive one or more locations from other clients and write them into the SER FIFO. If writing into the FIFO fails, try to write directly into the database (location-table, alias-table etc.). Report a temporary failure if this also fails. Maybe a centralized server should be used which receives the locations from the clients and distributes them to other clients, so that the nodes just know about the server and nothing about other nodes. This would make integration of new nodes easy. On the other hand, it's another single point of failure, so a decentralized solution should be considered. But that would mean that you've to inform every node about the existence of a new node. The protocol used between the nodes should be simple and fast. So I think SOAP drops out here. Maybe XMLRPC or ICE (http://www.zeroc.com/ice.html) could be used. One might think now why not just use replication on SIP layer, but t_replicate only supports one peer and you've no possibility to get locations on a node while it's down. Replication of other location tables like the alias-table is also not possible. I'd be willing to release these parts as GPL for creating an open framework for carrier-grade SER integration, so any feedback, improvements or flames are highly welcome. Cheers, Andy

[Users] auth ACK and BYE?
by Mark Kent 27 Sep '06

27 Sep '06

I just noticed that my SIP phone sends authentication credentials for ACK and BYE in a session where the INVITE required authentication credentials. I recognize this as a good thing... but it also surprised me. Currently, I don't handle it in my openser.cfg... I neither ask for the credentials nor do I strip them off before passing the message down the line... other than for INVITE. I'm going to correct this in my config, and I thought it worth mentioning for others just in case others also hadn't considered it. -mark

[Serusers] digit matching
by Richard C. Thompson 27 Sep '06

27 Sep '06

Hi All I hope someone can point me in the right direction or just give me a hint. I have the following route in ser.cfg and it works great. All I would like to do is change it so it matches on any number that starts with 002 regardless of length not just 12 more digits or a fixed length. if(uri=~"sip:(002............)@") I tried if(uri=~"sip:(002*)@") but it didn't work TIA Rick

[Serusers] Nathelper Ping OPTIONS
by olivier.taylor 27 Sep '06

27 Sep '06

Hello, just trying to enable the ping functionality in nathelper to send SIP message (i.e. OPTIONS) instead of 4-byte UDP packets on SER 0.9.6 and 0.10.0 as shown below, patch doesn't apply Is there another possibility to have this feature? Olivier patch -p1 < nathelper_ping.patch Hmm... Looks like a unified diff to me... The text leading up to this was: -------------------------- |diff -Naur -x CVS nathelper/nathelper.c nathelper_ping/nathelper.c |--- nathelper/nathelper.c 2006-08-16 08:45:48.000000000 +0200 |+++ nathelper_ping/nathelper.c 2006-08-10 14:54:14.000000000 +0200 -------------------------- Patching file nathelper.c using Plan A...

[Serusers] How to restrict only one call per user at the same time
by Ricardo Carvalho 27 Sep '06

27 Sep '06

Hi all, In an environment where the same user can be registered at the same time in multiple phones, how may I restrict users to only be able to make one call simultaneously? I mean... only make other call after hanging up the last one, never simultaneously made from different phones. How may I implement that? Regards, Ricardo.
