I find it strange that I can have to endpoints get audio went using bypass media mode but the audio fails to go across endpoints if I use proxy media mode.
I'm trying to pass audio "internally" on the same machine between endpoints and have be advised that a reason the audio may fail to be passed is because there is some RTP timing and IP address/port issues.
However, FS has no problem "connecting" ports if i change the mode to bypass media. This gives me the impression that something is wrong with FS proxy media mode.
Any comments?

It gives me the impression there is something wrong with your firewall running on the box.

With the firewall ON or OFF the problem still remains.

I've tried 3 different set-ups in a dial plan extension.

1. With only <action application="set" data="proxy_media=true"/> before bridging.

2. With only <action application="set" data="bypass_media=true"/> before bridging.

3. Neither of the above in the extension.

Only 2 with "proxy-media=true" gets the audio across endpoints.

Help

Try adding more ip to your box and give each thing it's own dedicated virtual IP.
Doing everything on the same box can be tricky.

Hi Anthony,

I actually suggested adding IP's to a Voxeo-Prophecy support person before but they thought that could be problematic. I went along with the earlier warning but now you have suggested it again. What makes everything on the same box tricky?

Also, the thing that surprises me a bit is that bypass-media works but proxy-media or the default doesn't.

Would you be kind enough to elaborate.

Thanks. Mark.

I don't really know what your problem is. I just saw you ask 3 times for help and tried to offer a suggestion.
if you start FS with TPORT_LOG=1 you can see all the sip messages in the console and you could
also run wireshark to look at a packet capture.

If you use the same IP for media on the same box for 3 programs at once you may end up with 2 applictions choosing the same media port etc.

It's just a good practice to run every voip program on it's own IP.

Mark,

Sorry I haven't had much time to help with this either.


But Anthony is offering good advice here. You are either going to have to work out what is going on at SIP/SDP/RTP level through logs and wireshark, or opt for a separate ip space. Another option (besides virtual ips) is VMWare or VirtualBox, although VMWare is probably easier to setup and bridge naturally to your host.


Vm's are just so easy anymore and it definitely seems like you are going against the grain right now.


Also - realizing you got here because of the need for ASR. I do have the Lumenvox license, and I was able to compile the module out of SVN. I have not tested anything yet. If things go well I should have some time after the 25th for this. My goal would be to get pizza or something akin to work.

Andy,

ping us when you are ready. we have a lumenvox version of the pizza thing already
That's the one we started with.

Hi Andy and Anthony.

Thanks Anthony for elaborating more and I'll attempt using another IP on the same box as well.

Also, Prophecy support has asked me first to put one application on a separate box and then get some wireshark data so I'll attempt that also.

Andy, I didn't want to bother you given all those things you had to deal with. Welcome back.

I explored the VMware idea before but was warned that it would not work well with an ASR. This advice came from the Trixbox forums, LumenVox, FreeSwitch and Voxeo.

I understand that what I'm doing goes against the grain (i.e. voip) but frankly my target market really doesn't want anything to do with voip or even internet connectivity from their businesses. Plus there are other issues.

I'll let you know how it goes.

Happy holidays.

Mark.

Mark,


This is great, a second box should help, you might want to go back to stock setups as well (ie none of the prophecy port changes, etc). This will help eliminate configuration error as an issue.

Anthony, will certainly ping you guys when I start testing. Thanks.

Hi Andy,

Yes, it works and I kept my port changes.

I tried the set-up in both "bypass-media" mode and what I've called "default" mode (i.e. no "bypass-media" nor "proxy-media" settings). Didn't try proxy-mode since the default worked.

The team at Prophecy is almost 100% certain as to what the problem is and which ports are involved. I've sent them the pcap and Prophecy log files.

Also, I was having background "crackling" noise in "bypass-mode" whether I ran FS in the box that it shared with Prophecy or if FS was running from the other box that didn't have Prophecy.

However, when I ran FS from the box without Prophecy in "default" mode then the audio totally cleared up??
