Sample extensions.conf and zapata.conf to try the behaviour:

extensions.conf
===============
[general]

[line1_in]
exten => s,1,Noop(Line 1)
exten => s,n,Wait(2)
exten => s,n,Answer
exten => s,n,Noop(${CALLERID(num)}: ${CALLERID(name)})
exten => s,n,Wait(2)
exten => s,n,MixMonitor(test)
exten => s,n,Hangup

[line2_in]
exten => s,1,Noop(Line 2)
exten => s,n,Wait(2)
exten => s,n,Answer
exten => s,n,Noop(${CALLERID(num)}: ${CALLERID(name)})
exten => s,n,Wait(2)
exten => s,n,MixMonitor(test)
exten => s,n,Hangup

[line3_in]
exten => s,1,Noop(Line 3)
exten => s,n,Wait(2)
exten => s,n,Answer
exten => s,n,Wait(2)
exten => s,n,Noop(${CALLERID(num)}: ${CALLERID(name)})
exten => s,n,MixMonitor(test)
exten => s,n,Hangup

[line4_in]
exten => s,1,Noop(Line 4)
exten => s,n,Wait(2)
exten => s,n,Answer
exten => s,n,Noop(${CALLERID(num)}: ${CALLERID(name)})
exten => s,n,Wait(2)
exten => s,n,MixMonitor(test)
exten => s,n,Hangup

zapata.conf
===========
[channels]
language=en
usecallerid=yes
hidecallerid=no
callwaiting=no
usecallingpres=yes
echocancel=yes
rxgain=4.0
txgain=4.0
immediate=no
hanguponpolarityswitch=yes
signalling=fxs_ks
group=1
context=line1_in
channel=1
context=line2_in
channel=2
context=line3_in
channel=3
context=line4_in
channel=4

As you can see from the log file, the problem is reproducable.

****** STEPS TO REPRODUCE ******

Just use the configuration files above, and dial into the first line.

The number I was dialing from was a cell phone, so phone number will be part of caller ID, but name is not.

Please try the 1.2 branch, there has been a major change to MixMonitor that should solve this.

please feel free to reopen if this was not fixed in latest 1.2 stable. Thanks.
