So glad you got it sorted. For the benefit of others... We exchanged some packet captures and discovered that the provider that did not proxy media, simply sent the SDP produced by Freeswitch back to Freeswitch. So Freeswitch was sending RTP to itself. Not a problem for a SIP point of...

In case this is of any interest, I just tried my first Debian 10 install on a test box (Debian 10.1). The install script threw the following errors: E: Unable to locate package php7.3-mcrypt E: Couldn't find any package by glob 'php7.3-mcrypt' E: Couldn't find any package by regex...

So everything is fine when Iristel IS proxying the media. Checking what IP addresses and ports are being written into the SDP bodies will be your only hope of diagnosing this. See if you can get packet traces of both calls that work and calls that fail and compare them.

So would I be correct in understanding that Iristel does proxy the media if the call is to or from outside the PBX, for example to or from a cell phone? When a PBX extension calls a DID, how to you stop it trying to place the call via Iristel? Do you use the is_local dialplan setting in the...

I am suggesting that we try to find out exactly what is wrong before working out where to adjust things. I don't quite understand what you mean by my provider doesnt proxy media. If you were to call my telephone number where would you send the RTP stream in order for my provider (BT Wholesale...

I would get a packet capture and see what is being written in the SDP Body, and look to see where the RTP streams are (~not) going/coming from.

This is a tricky one. A complete packet trace of a call may be needed to diagnose further, including the register and subscribe requests. The Record-Route process does have an affect how NOTIFY messages are constructed. You may have to dissect this a chunk at a time. Have you considered...

Sorry to ask the obvious. Are you sure 204 is subscribing to 203 correctly? Also what NOTIFYs do you get if you try the call the other way round, from 203 to 201?

Jeff, looking at your attachment, I only see the xml for direction="initiator". This is the notification of the invite from 201 to FS. When FS sends the invite to 203 you should also be seeing NOTIFYs with direction="recipient" for the other leg of the call. - Adrian.

Interesting that you don't see and NOTIFYs from FS on inbound. Are you certain that FS is not generating them? Where were you watching the traffic? Was it on the FS box itself? The reason I ask is because, if you are solely using UDP for SIP, a NOTIFY message can very easily exceed your MTU...

SIP 488 Not Acceptable Here most often occurs when two end points cannot find a common (mutually acceptable) codec to agree upon. However a 488 can also indicate that something else in the Session Description (SDP Boby) or indeed the Request URI itself, is not acceptable. Do you know if the...

A BIG thankyou Mark, we all appreciate your hard work.

That is good news. Is there any speculation as to when we will see the next stable release? I haven't found any mention on the Fusion members area.

Yes it does in 4.4.5. I was surprised!

Just checked this on our v4.4.5 test box and found that an Admin user can add a destination like ^016\d+$ which may or may not hijack another domains inbound depending on the processing order. See my switch log output. 67827b87-b86d-4c59-91a1-98435ef8a950 Dialplan...

On the production server you are starting to go into swap even though you have more memory than the dev box. Do you have any idea why? Like DigitalDaz, I am also very interested.

I'm not sure what you are asking. Maybe the regular expression to use for the condition in an outbound route? Maybe the dial string for a phone configuration? Whatever you are trying to achieve, you will probably find the Telephone Numbering Plan page on Wikipedia helpful...

I have no idea what could be causing this at present, my first thought was could it be related to codec transcoding? If you set an extension to call recording all, does the noise show up in the recording?

Thankyou @OLO Yes I was thinking of Pi4 with SSD, possibly as an on premises solution for small customers who are not yet ready to embrace the cloud. I hadn't thought of creating a cluster though - sounds like a good idea...

Would you share your installation method? Could you get packages or did you need to compile some components?
