Re: [Serusers] Get alias for user

But you can rewrite the user then.. if it comes user(a)ser.com and you rewrite to user_number(a)asterisk.com doesn't it work?

[Serusers] Urgent NAT question: mediaproxy,rtp or STUN ?
by Adrian Georgescu 20 Nov '05

20 Nov '05

Antonello, There is no better solution for all possible cases. The solutions have differences explained in the readme files for example RTP proxy can take more load per server, Media Proxy can distribute load on multiple boxes based on DNS SRV records and STUN can help your Stun enabled clients to traverse the NAT in majority of cases but not all. So a combination between STUN plus one of the relay solutions will cover all cases. Configuring per session when to use Stun or a media relay is quite a daunting task given the number of possible call flow scenarios so if you wish that your calls always work regardless of UA type or call flow you will enable a media relay because Stun is not reliable 100%. Adrian >>>>>>>>>> Terrible question: Is mediaproxy better than rtp or STUN server for NAT problem ??? Radius Authentication work fine with Mediaproxy, STUN and RTP ? In Mediaproxy Server, radius auth supported only in non-free version (7.000,00 euro) ! My work is: Private Network for more than 1000 users Public SER SERVER Public Radius+MySQL Public Patton MediaGW Please, answer ! Thanks Antonello

[Serusers] Multiple entries in Location Table with Same Call-Id.
by Ramu Yadav 20 Nov '05

20 Nov '05

Hi All, With Some User-Agents we are facing multiple entries in "location" Table. The main problem is each and every time UA sending register packet with different port number in the contact uri. I am here with attaching the location table values as well as traces. Thanks -- Ramu Yadav

[Users] How Effective is STUN?
by Tavis P 20 Nov '05

20 Nov '05

I'm trying to find some statistics as to what the ratio of Cone vs Symmetric NAT solutions deployed in the world are, has anyone done some research into this? I'm curious what percentage of users in certain demographics (broadband clients, for example) i can expect to be serviced using STUN alone, so i can come up with some figure to help me build out my network Even just some anecdotal information of peoples experiences would be very useful Tavis

Fwd: [Serusers] mediaproxy module: RTP packet mapping after reINVITE
by Adrian Georgescu 20 Nov '05

20 Nov '05

Hi Joel, MediaProxy development goes further. I will take a look at your observations and let you know if there is any duplicate effort. Thanks Adrian >>>>>>>>>> Anyone have a comment on the problem that I observe in which the mediaproxy receives a request for a session with a media description that has a new (rather than additional) connection address, but does not act upon it? Is there continuing work going on for this module? Here is my latest code which seems to solve the problem of a simple 1-audio-session call, while attempting to preserve the existing video add-on capability. Please excuse the clumsiness of the code as I am new to python. While it doesn't solve the general SDP management case, it does solve the simple and most common case of 1 audio stream. If the project leadership thinks this is useful, I can come up with a more complete solution and submit the code. However, if there is already ongoing work in this area, I don't want to duplicate the effort.

[Serusers] Mediaproxy on Multiprocessor System
by Adrian Georgescu 20 Nov '05

20 Nov '05

Your RTP generator process is also using CPU, this is why you see both loaded during the test. MediaProxy uses only one CPU. Adrian >>>>>> Hi All, I run mediaproxy on a 2 CPUs machine (Fedora Code 3). When I stress the mediaproxy with rtpgenerator locally, i.e., just rtpgenerator.py --count=50, I noticed that the load is distributed evenly between the 2 CPUs. But when I stress remotely, using a seperate PC, i.e., rtpgenerator.py --ip=x.x.x.x --proxy=y.y.y.y --count=50, where x.x.x.x is rptgenerator's ip and y.y.y.y is mediaproxy's ip, I noticed that the load is mainly taken by CPU0.

Tavis, Check out http://www.brynosaurus.com/pub/net/p2pnat/, it's not quite what you're asking for but it does include a table of data gathered from volunteers, detailing the percentage of NATs that support udp/tcp hole-punching and hairpin (loopback) translation. I'm concerned about the latter, it appears that not even ICE can resolve that issue.
