DTMF (I think)

New to Cingular Orange with a V551.

I am a former VZW user and my question is about the tones that are sent on
link dialing, numbers with a wait in between.

I had an LG phone when with VZW and when I sent the second set of numbers
after a wait the tones went through quickly, just as if you were using a
land line phone.

With my V551 on Cingular, each tone is are very long when it is sent. I
tried going to the settings and set DTMF to short but it didn't change
anything, the tones are very long when they are sent.

Is this because of the difference in the systems, GSM from CDMA? Is there a
setting in the phone somewhere to make the tones go out quickly?

Thank you for any replies.

I also wondered what was up with this, and have noticed the tone length
doesn't seem to be controlled with any handset option. In fact, almost
every time I use my 551 this way, the tone lengths are different,
whether they're manually pressed or part of a dial string. I've long
since quit worring about it because it doesn't seem to have any impact
on the success factor.

Here is a very good reply I got on wirelessadvisor.com from a "bobolito"

quote
It's because the Moto Vxxx phones have a slow processor. It's like a slow
computer struggling to catch up with the commands. If you try another
brand, like Nokia, LG, etc. you won't see this issue.

By the way, did you notice that GSM phones are smart enough to know when
the line is still ringing and will not send the DTMF tones until the line
is answered? This means you don't have to use pauses in the dialing string
to synchronize the time it takes for the line to be answered. On GSM, only
one pause is necessary to separate the phone number from the tones to be
sent and the tones will be sent at the right time no matter how long the
line takes to be answered. However, TDMA/CDMA phones often send DTMF tones
too soon or too late because they don't know if the line has been answered.
