[Asterisk-video] thanks for "help for videocall"

[barbara_b02 at libero.it]

Hi all
and thanks for your precious help!

I followed your instructions and I obtained:
3G -> SIP : video but no audio
SIP -> 3G : X-lite says "Call failed: Declined"

*This is my extensions.conf

[general]
static=yes
writeprotect=no
clearglobalvars=no
autofallthrough=no
videosupport=yes

[globals]
CONSOLE=Console/dsp
${TIMEOUT}=40

[default]
include => external_in
include => sip_out      

[sip_out]
exten => _0X.,1,Set(GLOBAL(CELL)=${EXTEN})
exten => _0X.,2,h324m_gw(dial at sip_to_cell)

[sip_to_cell]
exten => dial,1,h324m_call(dialcell at sip_to_cell)
exten => dialcell,1,Set(CHANNEL(transfercapability)=VIDEO)
exten => dialcell,n,NoOp(transfer=${CHANNEL(transfercapability)})
exten => dialcell,n,Set(CHANNEL(userinformationlayer1)=38)
exten => dialcell,n,NoOp(ul1=${CHANNEL(userinformationlayer1)})
exten => dialcell,n,Dial(mISDN/1/${CELL},40,tTkK)
exten => dialcell,n,Hangup()

[external_in]
exten => 191,1,Set(ul1=${CHANNEL(userinformationlayer1)})
exten => 191,n,h324m_gw(dial at cell_to_sip)

[cell_to_sip]
exten => dial,1,Dial(SIP/101,40,tTkK)
exten => dial,n,Hangup()

*My sip.conf

[general]
context=default
allowoverlap=no
bindport=5060
bindaddr=0.0.0.0
srvlookup=yes
videosupport=yes
maxcallbitrate_h263p=80 
disallow=all
allow=alaw

[101]
type=friend
username=101
secret=101
host=dynamic
nat=yes         ; ???
canreinvite=no 
accountcode=support
allow=h263p

*And this is the CLI during the SIP->3G videocall:

Dynamic payload.

I don't know if I have to set particular things in misdn.conf...

Thanks!
