Re: [Asterisk-Users] What does RELAXDTMF do?
Thanx for everyone's passionate responses, and apologises for not replying sooner. 1. Based on what I have seen I take it noone is sure of what the true purpose and the effects of the relaxdtmf parameter offer. 2. I am using both a mixture of VSP's and SPA3K's, but primarily it is the VSP's 3. And as for tweaking the output level's, I see no options being provided within the IAX and SIP configuration files, and not really concerned with the SPA3K's at this time since they are fail-overs. 4. Since the bulk of my issues are through the IAX2/SIP methods for DMTF and Asterisk has direct issues with DTMF, I just hope that v1.4 will be released sooner rather than later.

Re: [Asterisk-Users] What does RELAXDTMF do?
Doug, DTMF in a complex environment like this can break for many reasons. Please don't generalize your problem onto other people. He didn't say he was using the Sipura 3000 so we don't know for sure what his issue is. I am only saying this due to my own limited experience and how many ways I have found to break DTMF ;~) Marty ___ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Re: [Asterisk-Users] What does RELAXDTMF do?
Peter, Perhaps you have not followed the thread over the last few days about DTMF feedthru??? Here is what I sent out to another list kind of summing it up Regarding DTMF pass thru problems when using the SPA-3000 and *. The problem manifests itself as the inability to pass DTMF over the FXO to a PSTN call once the call is established. This would be used to call a bank, external voicemail or other service and use DTMF signaling to their service. To make a long story short (you can go thru the * mailist archives) this is an * problem in RFC-8233. It has been known for awhile and is being worked on in the form of a total RFC-8233 rewrite coming in 1.4 * hopefully this summer. Until then here is the fix I came up with. The FXO port Sipura setup (PSTN) should be set to INBAND for dtmf and the codec limited to g711u (or a), on the * side in sip.config FXO context set dtmf=inband and limit the codec to only g711u (or a) When you call yourself (say using your cell) and listen on the opposing phone hitting a key one listening on the other you should hear at least a half second or so of audible tone. Check this before and after changing these settings. Using RFC-8233 all I heard was a click and little or no audible tone. One other thing is that you CANNOT use features via tones over the FXO (TtWw,etc flags in dial). This is another broken issue in *. When you listen over the phone and hit a lead in character, defined in features.config, * mutes that character and it never gets sent. The correect action should be that it should mute it and wait until the second character. If the second character is not sent in a defined time then send the first character. This is not happenning. This might be an INBAND issue though and once RFC-8233 is fixed and can be used it might then work. If you have no need to send DTMF on a connected call via FXO then this change is not needed and you can use the current RFC-8233 as well as features. Just remember when you try to send DTMF over FXO port to PSTN that you know why it does not work!! This problem was/has been blamed on Sipura but is really an admitted * problem. It exists with other (but certainly not all) fxo devices also. As I said the best way to troubleshoot this is to actually call yourself and listen. Otherwise you are shooting in the dark and guessing. Doug On Thu, 8 Jun 2006, Peter J Dean wrote: I have an issue with DTMF.
