Re: [Openbts-discuss] OpenBTS with USRP2

[Tomas K. <de...@vo...>]

Hi,

you have to fix the config like that:

sip.conf

[IMSI404450510904785]	; IMSI chars must be added to digits, its OpenBTS hardcoded (from OpenBTS 2.5, if I'm right)
callerid=1001
canreinvite=no
type=friend
context=sip-external
;secret=1234		; don't use password on handset, it uses different type of authentication
;allow=ulaw		; use gsm codec
allow=gsm


extensions.conf:

[sip-external]
exten =>  1000,1,Dial(SIP/1000)
exten =>  1001,1,Dial(SIP/IMSI404450510904785)


Check OpenBTS/AsteriskConfig for samples. You don't need smqueue for 
calls, Asterisk handle that.
