<x-tad-smaller>Hi Everyone,</x-tad-smaller>
<x-tad-smaller>I know this may be off subject but I am not sure who to ask. I am currently looking for voip termination that is closest to replicating U.S. pots service. I run I.V.R. systems and I want to point Sipura 2100’s to a voip terminator and have the DTMF tones properly detected. All that I need is outbound service and the problem I run into now is that when the called party presses a key on the phone it does not play it back properly to my system. I have tried to dial through voxee and plain voip and they both have the same problem. Im not sure if this is an asterisk issue or what. When I dial through packet 8, aptella or vonage everything works fine. I think my problems are because I am going through their asterisk servers. If anyone can help I would appreciate it, there is a potential for me using thousands of minutes per day if I could only find compatible service.</x-tad-smaller>
<x-tad-smaller>I use the generic term U.S. Pots service because my dialers work perfectly on normal analog phone lines. I’ve been looking for service for 2 months and I haven’t had any luck.</x-tad-smaller>
<x-tad-smaller>P.S. I do not need any special services, just proper DTMF tone handling.</x-tad-smaller>This might be a codec negotiation issue with the termination service. I am using Teliax with my asterisk server to terminate my SIP and IAX calls from several ATAs and softphones. All of that works fine with DTMF.
I am using the G729 codec exclusively for my Teliax calls. You also need to be sure that the extensions for each ATA/phone have the DTMF configured righteously.
HTH,
