Options to support an old rotary pulse dialing telephone?

[jeffrey.girard]

My wife found an old phone in an antique shop.  Its the kind where the earpiece is on the side and you hold it up to your ear and then speak into the fixed mouthpiece.  Someone retrofitted it with a rotary pulse dialer device inside the case.  I connected the old 2 wire tip/ring to a POTS line from my PBX and it will receive inbound calls fine.

Other than some aftermarket devices to (inline) convert the pulse to DTMF, does anyone know of a way to support rotary pulse dialing with IP Telephony?

My wife would really like this phone to be functional in our house

Hi Jeff,

For a FXS port/interface, Pulse or DTMF dial detection is automatic on inbound calls to a voice-port. 

For outbound dialing though, that's physically impossible (a FXS port can't go offhook/onhook). 

DTMF is the only solution for outbound calls. 

VG224 will support pulse dialing only in H323 mode. For MGCP, there is no support yet.

Use the dial-type command to specify an out-dialing type for a Foreign
Exchange Office (FXO) or E&M voice port interface. This command specifies the tone type for digit
detection and out-pulsing. This command is not applicable to Foreign
Exchange Station(FXS) voice ports because the ports do not generate
out-dialing. This command also specifies the detection direction. Multifrequency tone dialing is not
supported for FXS and FXO. 
 
Voice ports can always detect DTMF and pulse signals. This command does not affect voice port dialing detection. 
 
The dial-type command affects out-dialing as configured for the dial peer. 
 
If you are using the dial-type command with E&M Wink Start signaling, use the dtmf or mf option. 
 
SGCP 1.1+ does not support pulse dialing. 

The following example shows a voice port configured to support a rotary (pulse tone) dialer: 
 
Router(config)# voice-port 1/1
 
Router(config-voice-port)# dial-type pulse
 
 
The following example shows a voice port configured to support a DTMF(touch-tone) dialer:
 
Router(config)# voice-port 1/1
 
Router(config-voice-port)# dial-type dtmf
 
 
The following example shows a voice port configured to support a multifrequency tone dialer: 
 
Router(config)# voice-port 1/1
 
Router(config-voice-port)# dial-type mf

please rate if this helps

I know this is an old post, but I thought I'd reply with some information.

I am successfully running a 1929 Western Electric model 102 "B1" rotary phone on a VIC3-2FXS/DID card.

This is in a 2821 ISR router with CME on 12.4(24)T8. It's in a lab, so I am not connected to the PSTN.

The card accepts the pulse dialing by default. I can send and receive calls to a 7941 phone. It will not send DTMF during the call, so don't expect to navigate any call handlers.

I did have to set the ring frequency to the lowest setting to get it to ring. Even then, the ring is not very loud. Of course, that may be because the phone is ~84 years old.

voice-port 0/2/0

ring frequency 20

Thanks, Randy
