I think this is a tricky one!

As far as i can tell, you'll need to write a custom chatscript to dial
those numbers before running wvdial. This is just a rough guess at such a
chatscript:

######### START CHATSCRIPT #########

# Set ABORT settings for dialing the forward thing
CLR_ABORT BUSY
CLR_ABORT 'NO CARRIER'
CLR_ABORT VOICE
ABORT 'NO DIALTONE'
ABORT 'NO DIAL TONE'
CLR_ABORT 'NO ANSWER'

# Stick the init string here.
'' ATZ

# Dial the forwarding code.
OK ATDT*72xxxxxxx
# Wait 5 seconds or so...
'' \d\d\d\d\d\d
# Hang up and do it again.
'' +++
TIMEOUT 5
OK-AT-OK ATH0
TIMEOUT 45
OK ATDT*72xxxxxxx
'' \d\d\d\d\d\d+++
TIMEOUT 5
OK-AT-OK ATH0

# Your calls should now be forwarded...

########## END CHATSCRIPT ##########

You'd then run wvdial as normal.

After wvdial disconnected, you'd use another chatscript something like
this:

######### START CHATSCRIPT #########

CLR_ABORT BUSY
CLR_ABORT 'NO CARRIER'
CLR_ABORT VOICE
ABORT 'NO DIALTONE'
ABORT 'NO DIAL TONE'
CLR_ABORT 'NO ANSWER'

# init string...
'' ATZ

# Dial the *73 thing, wait 5 seconds, and hang up just like before
OK ATDT*73
'' \d\d\d\d\d\d+++
TIMEOUT 5
OK-AT-OK ATH0

# Your calls should now be unforwarded

########## END CHATSCRIPT ##########

Since wvdial doesn't background itself, you could turn this whole thing
into a shell script

- -----------
#!/bin/sh

# Crude hack to use the chatscript... Anyone know a better way?
pppd noauth init "chat -v -f /path/to/first.chatscript && false" \
  /dev/ttyS2 nodetach

# run wvdial
wvdial

# repeat of crude hack with other chatscript
pppd noauth init "chat -v -f /path/to/second.chatscript && false" \
  /dev/ttyS2 nodetach

- -----------

Of course, i don't guarantee this will work at all... And it might not
even be the best way to do it.
