[mujib.alu]

HI,

Any one success SIP trunk with Rel 7.1 for DID/DOD interface,

In my case,

Calls are getting connected In/Out but Incoming (DID) one way speech, Ougoing (DOD) No speech.
Any idea..?

Check you LAN - RTP traffic allowed or not, NAT not used?

[mujib.alu]

OXE is stand alone, No IP Phones and Nat used

OXE, INTIP2,Cisco Router and PC only available in the switch, CISCO router F/E0 conected with LAN, F/E1 connected with SP Modem (SIP),

In router NAT configured, 5060 ports allowed.

if you need further i can provide..Please help..

Hi Murraya,

Actually Nating availbale at router only,

Cisco is nating local IP@ and SIP Public IP@, Also it's get connected, Ping possible each other ( CPU,INTIP2,PC,Router,SIP Signal IP and Provider Router).

After all these OXE can reach DID and DOD calls but without voice packet's

Scenario...
IF the call from Service provider (DID) one way speech presents(Public user can hear the OXE user voice)
If the call made from OXE to the public user No speech..

Service provider blaims to the OXE..

If you need any traces i can provide

Again Rel 7.1 will support the SIP Trunk ..? ( but i got the License through ACTIS)

Note : same location SIP DID/DOD working succefull with OXE release9.1.

Again, SIP doesn't work with NAT, headers are different, you need something on the middle to transform them in supported headers. Mainly what happens is that OXE sends packets with internal IP Address but the other side have no idea on who it is because it knows the public ip address only.

[mujib.alu]

I hope, to transform the header, From Service provider SBC available which is providing the SIP server IP and provider Router IP@

Note : ame area OXE(9.1), Cisco Router and SIP Provider Equips(SBC) working successfully..

Hi,
How did you manage to get a license for NeoSBC? I've been trying to do that but the product seems to be discontinued.
