[Asterisk-Users] Help with dialplan

[Cosmin Prund]

I've got a Mobile-to-PBX gateway installed and I want the ability to dial
from my mobile phone into my PBX and next dial a land-line from the PBX so I
can make cheep mobile-to-land-line calls while on the go.

I've contemplated using the WaitExten application but it only seems to wait
for ONE digit! Is there a way to put the calling mobile phone into a context
and wait for a full-length extension?

Thanks!
