[Asterisk-Users] Advanced WaitForDigits

[Christian Gröger]

Hi,
I am using some ISDN Phones with my Asterisk, there are some outbound 
routes to sip and to the telco, that make it necessary to dial >10 
numbers sometimes. But sometimes if you need some more time to look for 
the number the timeout in WaitForDigits is exceeded and it tries to dial 
the too short number. Is there a more advanced possibility, that somehow 
detects if the number exists or something?

btw. Can Asterisk recognize pulse dial tones?

Thanks,Chris
