[Asterisk-video] Is it possible to pass through two asterisk ?

[오상수]

Thanks your advice :-) 
 
I had already tested below two case senerio 
 
SIP<-->asterisk<--->SIP (voice, video)
 
SIP audio<-->asterisk<-->DAHDI-E1<-->asterisk<-->SIP audio
But I didn't test case which was related by 3G mobile phone
 
What dose it need ? 
--> devices or setting
 
Dose Telco's help need ?

Yes it is possible. But I suggest that you start from the beginning, e.g:
SIP<-->asterisk<--->SIP
3G mobile phone <-->asterisk<--->h324m_loopback()
3G mobile phone <-->asterisk<--->h324m_gw<-->echo()
3G mobile phone <-->asterisk<--->SIP
SIP <-->asterisk<--->3G mobile phone
SIP audio<-->asterisk<-->DAHDI-E1<-->asterisk<-->SIP audio
only if you manage all of the above scenarios to work successful, then
try video from Asterisk to Asterisk.
I think you will experience high delay.
Start with Asterisk 1.4. on 32bit Linux as it is more tested as 1.6 and
64bit.
