Jio Sip trunking with asterisk

  About JIO SIP trunk :

           Reliance Jio Leading telecom vendor in INDIA, who also provides ISDN/E1 trunk via Ethernet in SIP Protocol (ie VOIP) to customer similar to SIP trunk provided by TATA/AIRTEL.
    As shown in the picture below JIO provides a dedicate network to connect to there SIP gateway to register the SIP trunk.
Either you need to have dedicate ethernet port in asterisk server to connect to jio network, or redesign the network setup to opt to JIO subnet.

jio sip trunk lan settings

  JIO sip trunk details:

            Once you have purchased  the new jio sip trunk, you will be provided with below details

DID numbers
Pilot number
SIP gateway IP & Media IP
Jio Network subnet range (server IP,subnet, gateway IP)

  Step 1: Network Connection

            As show in picture above ,connect your Asterisk server to the JIO network and assign the IP address from the subnet provided by jio either to a second ethernet or existing ethernet port(based on your network design).
The network configuration is not covered here , it might defer between OS type you are using, but concept is same.

  Step 2:  JIO SIP Proxy Static route

       If you are connecting JIO to your existing networks as pre the picture shown, then you might need a dedicate route to reach the JIO SIP Proxy also media ip.
Strict RTP switching to RTP target address 
Check your OS network settings to set static route to jio network.
Sample JIO Sip details

SIP proxy ip    :
Media IP          :
ServerIP           :
gateway ip       :
interface           : Eth1
Centos 7 command to set a static route to SIP proxy ip and media ip
ip route add via dev eth1
ip route add via dev eth1
Command to check the routes
ip route show 
route -n

  Step 3: JIO SIP peer configuration sip.conf

     Once you have setup the network , make sure you are able to reach the JIO gateway and SIP gateway ip by ping command.
       enter the below sip settings in you asterisk sip.conf,  if are using Freepbx you can create the same in Gui trunk settings, similar for vicidial/goautodial under carrier settings.

host=100.XXX.XXX.XXX ;this is jio sip proxy ip
fromdomain=100.XXX.XXX.XXX ;this is jio sip proxy ip
context=from-trunk  ;context to receive inbound calls

  Step 4: asterisk dialplan for jio sip

Note: The key factor to dial out via JIO , you need to set proper caller-id while dialing out.
Use the below dialplan , alter according to your requirement.
For vanilla Asterisk :

exten => _X.,1,Set(CALLERID(num)=+914412345678)
exten => _X.,2,Dial(SIP/jiosiptrunk/${EXTEN})
exten => _X.,3,Hangup
;+914412345678 is my pilot no, you have to enter your pilot no or any number from the DID range

Vicidial / Goautodial
exten => _X.,1,AGI(agi://
exten => _X.,2,Set(CALLERID(num)=+914412345678)
exten => _X.,3,Dial(SIP/jiosiptrunk/${EXTEN},,tTo)
exten => _X.,4,Hangup
;+914412345678 is my pilot no, you have to enter your pilot no or any number from the DID range


    If  you want individual CID for each user make sure each user extension is configured with outbound callerid with there DID number. 
For Freepbx, you need create outbound route , with necessary Dial pattern and make sure to set the ROUTE CID (either pilot or DID numbers)


Hope the above tutorial is helpful to configure the JIO siptrunk in your sip server.

    With Jio SIP trunk, both incoming/outgoing call are working.
    Only problem is incoming call disconnects are 5-6 seconds. Even both parties can hear each other. What could be the reason. Please suggest

      Sorry i could not reply you back. Anyway i have sorted out the voice issue by disabling NAT under Asterisk SIP Settings.
      But is there any other work around for this. Actually i want to keep NAT enable for calling from outside as my PBX is running behind firewall.

      disable nat to specific trunk
