Key R detected sometimes

Asterisk Asterisk Support
1

Hello,

I have 2 different analog phones conected to a TDM22B, in channels Zap/1 and Zap/2. I’m using Asterisk 1.2.4 with zaptel 1.2.4.

I one of these phones, I can make the basic operations with the R key (put on hold, transfer, and answer 2 calls at a time). When I press R, a “Wink/Flash” event is sent, the logs are:

Mar 13 16:56:17 DEBUG[25821] chan_zap.c: Exception on 14, channel 1
Mar 13 16:56:17 DEBUG[25821] chan_zap.c: Got event Wink/Flash(3) on channel 1 (index 0)
Mar 13 16:56:17 DEBUG[25821] chan_zap.c: Winkflash, index: 0, normal: 14, callwait: -1, thirdcall: -1
Mar 13 16:56:17 DEBUG[25821] chan_zap.c: Already have a dsp on Zap/1-2?
Mar 13 16:56:17 DEBUG[25821] chan_zap.c: Swapping 2 and 0
Mar 13 16:56:17 DEBUG[25821] chan_zap.c: disabled echo cancellation on channel 1
Mar 13 16:56:17 VERBOSE[25821] logger.c:     -- Started three way call on channel 1
Mar 13 16:56:17 VERBOSE[25821] logger.c:     -- Started music on hold, class 'default', on Zap/3-1

But in the other phone, when I press R, the event sent is “Pulse Start”:

Mar 21 16:47:53 DEBUG[18922] chan_zap.c: Exception on 14, channel 1
Mar 21 16:47:53 DEBUG[18922] chan_zap.c: Got event Pulse Start(14) on channel 1 (index 0)
Mar 21 16:47:53 DEBUG[18922] chan_zap.c: Exception on 14, channel 1

Mar 21 16:47:53 DEBUG[18922] chan_zap.c: Detected pulse digit '1'

Mar 21 16:47:53 DEBUG[18922] channel.c: Bridge stops bridging channels SIP/104-7120 and Zap/1-1
Mar 21 16:47:53 DEBUG[18922] res_features.c: Feature interpret: chan=SIP/104-7120, peer=Zap/1-1, sense=2, features=2

I have resolved this issue making “#” the key to attender transfer, and “**” to blind transfer (both in features.conf), but I don’t know how to configure the “hold” key.

My questions: why the R key is not the same event in both telephones? What kind of event is “Pulse Start”? How can I make the R key work in the second telephone?

Thanks in advance.
