[c-nsp] SIP to T1

[Brian Turnbow]

Hi guys,
Cisco does support overlap dialing 
You can use 
 isdn overlap-receiving T302 3000 
On the isdn interface T302 is the ISDN interdigit timeout it waits before starting the call.
In this case it sets it to 3000ms.
You need to find the best mix between introducing call delay and getting all the digits collected.

Hope it helps
Brian

Thanks Tim, At the time we bought the PBX it was a matracom PBX  Today
the label on the PBX  would be named "nortel".  The vendor told me he
enabled such a feature but it didn't work out. perhaps cause  the
length of a number could be different (from 3 digits up to largest
international number) and I do not know wht is realy configured on th
PBX. I'll have a look on the PBX an with the vendor.

Thanks
