Voice Gateway: TCL script and ISDN overlap receiving

Dear Community,

we would like to use a TCL script on an inbound POTS dial-peer. The script should play an announcement to the caller and then forward the call to the original dialed number.

The PSTN connection uses E1/primary-net5.

The script works fine so far, however it fails in case of overlap receiving. For some incoming calls we still need overlap receiving, i.e. the initial called number in SETUP is incomplete, additional dialed digits are transmitted in individual ISDN INFORMATION messages.

--> Is there a way for a TCL script to handle the overlap receiving case correctly, collecting additional dialed digits (until it reaches four digits in our case) or until a timeout occurs?

Thanks in advance for any suggestions/examples.

BR

Hi yawchen - thanks for the link.

The text/section refers to VoiceXML applications only - it does not mention TCL explicitly.

So I guess this restriction is also applicable to TCL right?

It applies to Tcl too. Tcl and VXML APIs are based on the same framework
