Do some users have public and some private? You may be able to get away with reinviting internally.

I have heard of problems previously where users were using softphones and they were introducing the echo. Switching to hardphones solved it and narrowed down the problem ;)> Thanks for any help you can give meYou're welcome and hopefully some others can give some insight and maybe information on their own deployments similar to what you wish to do.> Carlos Bernat > >Joshua Colp Digium

[asterisk-users] Developing VoIP with Asterisk
Hi Group! Still I'm concern about my problem with echo on the voice and I want to ask some advice to developing VoIP. Maybe I'm very ambiciuos or maybe not because I want to give VoIP to near 500 users. We got an small ISP and we have the project to give telephony (for now) to our users between them. Our resources are limited and I have installed * as a hope to give this service to our users. We have a good network (with small problems) but I believed that is possible to give this service. Our HFC network is very well calibrated and works fine. The users have cable modems to connect to the internet and we give private adresses to some users. I'm searching for someone who has the same problem in the past with similar things, to know how solve it and if is possible to give VoIP calls with a server with a public address and the softphones (for the costs) with extensions registered on our * box. I configured * four months ago and between two extensions and works very well and but later I did the same test on this week and unfortunaly the voice goes out with echo. So I have the feeling that maybe there's something wrong with the codecs and wich codecs do I need to give the service. Thanks for any help you can give me Carlos Bernat -------------- next part -------------- An HTML attachment was scrubbed...

[asterisk-users] Developing VoIP with Asterisk
Hi Group! Hi Wagner! Thanks for the interest. I'm from Colombia and I'm trying to develop VoIP as you know on *. So thanks again for the offering in Brazil, althought you can help me with some idea by this way. To make the call I'm using SJphone (softphones) to make the tests. I'm not using IP phones because we don't have a lot of investment as a said before. This is my [general]sip.conf format: I omitted other parts which were on comments because it is example from the web site [general] context=default ;allowguest=no ;realm=mydomain.tld bindport=5060 bindaddr=0.0.0.0 srvlookup=yes ;domain=mydomain.tld ;************** Cambio de lineas disallow=all ;allow=g729 allow=gsm allow=ulaw jitterbuffer=yes maxjitterbuffer=800 ;allow=ilbc ;musicclass=default ;language=en ;relaxdtmf=yes rtptimeout=60 ;rtpholdtimeout=300 ;trustrpid = no ;sendrpid = yes ;progressinband=never ;useragent=Asterisk PBX ;promiscredir = no ;usereqphone = no ;*********** Cambio de lineas DTMFMODE estaba en comentarios ******************** dtmfmode = rfc2833 ;compactheaders = yes ;sipdebug = yes ;subscribecontext = default ;notifyringing = yes ;******************** Usuario 1 ************************ [usuario1] type=friend host=dynamic dtmfmode=rfc2833 username=usuario1 secret=usuario1 ;******************** Usuario 2 ************************ [usuario2] type=friend host=dynamic dtmfmode=rfc2833 username=usuario2 secret=usuario2 Thanks again for the interest and if you have and idea I would apreciate a lot!
