[asterisk-users] Rotary
phone on Asterisk</span></font><o:p></o:p></p>

<p class="MsoNormal"><font face="Times New Roman" size="3"><span
style="font-size: 12pt;">I'm trying to use a couple of old Western
Electric type 500 phones
(desk model, rotary dial). These phones work fine, as tested with
telco
lines (they dial, receiver/transmitter works fine, etc).<br>
<br>
I'm running Asterisk 1.6.2.11.<br>
<br>
I can't get them to dial through Asterisk. They are connected to a
Rhino
channel bank which is connected to Asterisk via a Sangnoma card (T1
with echo
cancellation). Other phones (touch tone) work fine, as does any phone
with a pulse/tone switch, even when these electronic phones are in
"pulse" mode.<br>
<br>
I'm thinking that Asterisk is a bit too picky about the timing of the
rotary
dial pulses to handle a mechanical system. Is there any way to correct
this?<o:p></o:p></span></font></p>

Better read the link<br>
That refers to the TDM400 card. Posted to voip-info quite a few years
ago, I believe it MIGHT have made it into a recent release, or coming
soon.<br>
<br>
For T1 though, I believe the channel bank might be the issue.<br>
We have several channel banks of various types with various T1 cards.
Adtran 750's aren't supposed to work properly, according to Adtran,
other companies do. <br>
Better ask Rhino first, as the pulse detection and timing is a channel
bank issue.<br>
<br>
500 sets are pretty good with pulse speed and make/break ratio. The #9
dials are even better than the #7 ones, though all are fairly stable. <br>
Older phones, WE or others, can be more difficult, and may need to be
repaired.<br>
