Problem to dialing out Freephoneline.ca with Asterisk

[fazer]

Hello,

I have a weird situation with freephoneline.ca when i try to connect to a call center phone.

I have 3 trunks to my pbx box (trixbox/Asterisk) and i have only a problem with freephoneline.

When i try to calling a company with a choice to different department, it's impossible to make a choice. I'm claaing the company without problem, when it's a time to make i choice, example, 1 for English, 2 pour Francais impossible to make a choice.

I make a test intranl and all is good.

Do you have a solution for this issue ?

Thanks,

Fazer.

dtmfmode=auto on the trunk works for me. No problems with FPl and automated attendants. My sets all have dtmfmode=rfc2833.
