Hello all

My latest implementation of Trixbox was an upgrade on a factory that already had plain phone devices (not IP devices). In order to keep the cost down i choose to use Grandstream GXW-4024 as a solution. The problems i was originally faced with were a lot but after flashing the devices with the latest firmware most of them were solved. (now running on: Software Version: Program-- 1.0.1.41 Bootloader-- 1.0.0.9 Core-- 1.0.0.37 Base-- 1.0.0.87)

The only one that i haven't cracked yet is passing all the * feature codes from the 4024 to asterisk. Although i have included on the dial plan of the 4024 the: {[x*]+} and that seemed to solve some of the * features i still can't make the attended transfer "*2" to work. I noticed though that while i was logged on the asterisk CLI and made a call on another extension i pressed the *2 digit to make the transfer and noticed that asterisk won't listen to the *2 digits being dialed. The other end can hear the *2 but asterisk won't and that is why some of the * feature codes don't work.

Another is: i dial *97 to my voicemail and though i hear the asterisk lady saying: "password" which prompts me dial my password asterisk will not listen to the digits that i press. (that is i assume because GXW-4024 is not passing them)

Another: The *8 code that is to pick up a near by ringing extension works just fine because the digits are passed from the GXW-4024 to asterisk.

So to conclude i need some settings (if there are any) that will allow the GXW-4024 to pass dial tones to asterisk WHILE there is a phone call in progress. I assume that this will solve all my problems

Thank you for your time

Ok cracked that one as

Ok cracked that one as well

On the GXW-4024 i just changed the "Preferred DTMF method:" setting to "RFC2833" and voila! all works just fine. Previous setting was "Audio" so i guess that is why asterisk couldn't hear the tones.

I had the same issue, but it had to a couple things. First I had to change DTMF tone to RFC2833 , or you can try SIP INFO, see which one works best. Then it happens to be a dial plan, I changed it
to { x+ | *x+ }, so it passes through everything, or you can be more specific { *xx|*xxx|[3469]11|0|00|[2-9]xxxxxxxxx|1[2-9]xx[2-9]xxxxxx|xxxxxxxxxxxx.|011xxxxxxxxxx}
