[Asterisk-Users] Multiple Line config help

[kurt x]

I have aSIPURA 841 that is working on L1 with phone # 4027.  L2 is
configured for 94027.
Both numbers register with Asterisk.  When issuing the command "sip show peers"
both numbers have the same IP address but 94027 show its sip port at
5061.  Which I expect is right.  When I dial 4027 it works but when I
dial 94027 I get a "486 busy here" and voice mail picks up.

config below:

sip.conf
[4027]
type=friend
host=dynamic
dtmfmode=rfc2833
context=home
callerid=SIPURA-L1
canreinvite=no
mailbox=4027 at local

[94027]
type=friend
host=dynamic
dtmfmode=rfc2833
context=home
callerid=SIPURA-L2
canreinvite=no
mailbox=4027 at local

extensions.conf
exten => _40xx,1,Answer
exten => _40xx,2,Dial(SIP/${EXTEN},10,t)
exten => _40xx,3,Voicemail(u${EXTEN})
exten => _40xx,4,Hangup
exten => _40xx,103,Voicemail(b${EXTEN})
exten => _40xx,104,Hangup

exten => _940xx,1,Answer
exten => _940xx,2,Dial(SIP/${EXTEN},10,t)
exten => _940xx,3,Voicemail(u${EXTEN})
exten => _940xx,4,Hangup
exten => _940xx,103,Voicemail(b${EXTEN:1})
exten => _940xx,104,Hangup

Thanks,
