DRG box and dialing to modem with post digits

[doktor]

Hi All

I have an issue with the DRG22i box (ATA-box - analog to VoIP converter).
It is OK to dial from my laptop with an external modem through the DRG22i box to a remote modem (e.g. an MD110).
Signalling is OK an so the performance.
BUT if I want to send extra digits (post dialing digits) when e.g. calling a Voice 200, then it fails.
Calling this application you need to send post digits - after the remote application has answered.
To dial this application: ATDT0xxxxxxxx,,,,,,###5
Where the commas indicate a 1 second pause and the ###5 will start the modem in the application.
Any hints?
