Hi

I have installed the asterisk 11.4 and made video,voice call in local wifi seuccessfully.

No I have configured the same in a remote server with a public ip. I can ping the server and no firewall enabled in server os ubuntu.

My setting:

sip.conf:

[1000]
secret=1000
type=friend
host=dynamic
context=local
qualify=yes
canreinvite=no
nat=no
disallow=all
allow=ulaw
allow=g729
allow=gsm
allow=ilbc
allow=speex
allow=h263

[2000]
secret=2000
type=friend
host=dynamic
context=local
qualify=yes
canreinvite=no
nat=no
disallow=all
allow=ulaw
allow=g729
allow=gsm
allow=ilbc
allow=speex
allow=h263

extensions.conf
[local]
exten => _XXXX,1,Dial(SIP/${EXTEN})

Sip peer is getting registered bu unable to make call.

What i need to do?

Try asking a forum that it intended to provide support, not one intended for discussions.

Check your NAT settings. Check the NAT settings on the router. Disable any SIPALG on the router. Re-check for firewalls.

Obtain SIP traces and see exactly which request or response is being retransmitted.
