Hi All,

I am using usrp2 board, ubuntu 11.04 on which i am running GNU radio 3.3.0 with UHD 003.002.003, OpenBTS 2.8p and asterisk 1.8.3.3 and i am trying to register a phone to the network, but i am unable to register my phone. when i give the command tmsis on the openbtscli i can see the IMSI of the phone but i am not able to register.

In Openbts.example.sql i have changed

GSM.Radio.Band - 1800
GSM.Radio.C0 - 880

In my sip.conf i have added the following :

[IMSI405803180005242] ;N95 detected
callerid=2105
canreinvite=no
type=friend
context=sip-external
allow=gsm
host=dynamic
dtmfmode=info

In extensions.conf i have added the following :

[sip-external]

exten => 2105,1,Macro(dialGSM,IMSI405803180005242) ;N95 detected

Is there any thing which i am missing. Thanks for your time. Thanks.
