Our trixbox 2.6.2.3 has been spot on, on recent calls into our system via POTs line to TDM404 card (if not answered) they go out via TDM card to a GSM gateway (nokia) to our cell phones. Recently the audio quality has been poor when the call has been brigded.

Anybody had this, and know why ?

Where are you hearing these

Where are you hearing these issues? I assume on your cell phone...

Perhaps its not the Trixbox, but sometimes cell connections arent so amazing?
Its also possible that on the GSM gateway it could have an issue.

basically, you have a lot of parts that could be the issue, and since its random and not on every (is it most calls?) calls then its gonna be hard to localize.

I suggest start backwards:
1)Next time it happens, I assume you will be on your cellphone - look at your connection
2) Reposition the GSM gateway
3)check the cables
4)check the card

goodluck
