Very New in Asterisk

Hi,

I downloaded asteriskNow iso and successfully installed the system. after that i added two simple user in sip.conf

[selcukyazar]
type=friend
fromuser=selcukyazar
host=dynamic
secret=********
callerid=“Selcuk YAZAR”
context=trakya
username=selcukyazar
mailbox=selcukyazar@trakya.edu.tr
disallow=all
allow=ulaw

[deniztaskin]
type=friend
host=dynamic
fromuser=deniztaskin
secret=********
context=trakya
callerid=“Deniz TASKIN”
username=deniztaskin
mailbox=deniztaskin@trakya.edu.tr
disallow=all
allow=ulaw

and also added values extensions.conf like below
[trakya]
exten => 1234,1,Dial(SIP/deniztaskin)
exten => 4321,1,Dial(SIP/selcukyazar)

so, i can successfuly calls from my android phone with zoiper to another android phone. but we can’t see the caller name always show client account name. we want to use asterisk only internal network calls. what is the problem

thanks in advance

fromuser should not be needed.
