1st CellPhone-->2ndCellPhone-->DocknTalk-->Sipura30

[OV]

it was a combination of Sipura and Dalk-n-Talk. It works great with another GSM GW.

Is this broadly confirmed with all CDMA users?
Any CDMA users have no problem?

I am on Sprint CDMA and have been considering this, but this gives me room to doubt and lean away from the SPA-3000/DockNTalk.

I wonder if the other solution of the FX-200+SPA200 (while I don't understand exactly the pros/cons of how this differs from the SPA3000 implementation) would work, of if the problem is with the DockNTalk.

I have also been on the phone with Woodtel discussing their CM1003 solution, that would require no DockNTalk, only a cell phone with free incoming minutes...I am still weighing pros/cons...

We are working at my company with gsm-gsm-dnt-spa3000-asterisk solution.
after many attempts of dtmf recognition with no luck, we decided to try with software solution instead of dtmf detect on the spa3000.

Asterisk inband dtmf detection doesnt work too.

We found a software alternative, recording the tones and decoding through tt-dec, an open source dtmf detection software.

http://sourceforge.net/projects/tt-dec

We change some parameters of the code regarding minimum dtmf tone time and it works!

hope this can help for the cdma guys,,,
