[Asterisk-Users] SIP phones supporting early dial

2005-11-04 Thread Chris Bagnall
Hello all,

Is there a list of phones that reliably support SIP early dial? One of the
really nice things I've noticed about the 7960 (SCCP) is that each digit is
sent straight to asterisk, so when the number has been completed, connection
is almost instantaneous. I've tried early dial on both the GXP2000s and the
HT486/488 units, none of which seem to work reliably.

Regards,

Chris

Not that I know of, but the Polycoms support their own digitmaps, which 
pretty much makes sure the call is dialed when you are done dialing.

As I recall, the budgetone's support early dial as described, but that
doesn't make it a good idea. The Cisco SIP firmwares also support their
own 'digitmaps' as described above, in the form of dialplan.xml. Easy to
set up, probably easy to automatically generate if need be.

SCCP and SIP are very different approaches to endpoint control. Look how
chatty SCCP is compared to SIP...

Anyway, add Cisco SIP firmwares on the 7940/60 to the list, at least.
