I am connecting Panasonic TDE600 to Samsung OS7400 ver 4.75 via SIP PEERING. I donot know how the Panasonic tech did his configs but he is dialing 7 to pick his SIP trunks and dial an extension e.g. 2600 on the Samsung. Surprisingly the call rings to the operator group 5000 bypassing the Auto attendant group set for all trunks to ring and violating the DID settings on the PBX.
When I call from the Samsung, I get an IP NETWORK FAILURE response. Please assist with possible solutions to overcome this.

The reason his call rings to the operator is that he is sending a number which isn't in your indial table.

The display on the operators phone will show what number he is sending (i'm guessing it's the direct extension number like SPNET does).

The samsung isn't able to establish a call to the panasonic via sip.
You are going to have to wireshark the OS7400 to see what response (if any) it's getting fron the panasonic.

I've done this before between a OS7400 and a panasonic (can't remember the model).

ok will try that
thanx

what he had done is he had set a panasonic softphone with CLI name SOFTPHONE and thats the one showing on the keyphone. it is not showing its source extension no. which is 4697.

I have run wireshark and the craziest thing is the samsung os7400 is not showing any SIP activity, no INVITE whatsoever. When i run a port scan, 5060 is shown as closed. I took a boxed OS7070 ver 4.82 and its behaving the same. it receives incoming calls but when calling frm samsung, it will show IP NETWORK FAILURE. Please help for sip to show

Are you running the wireshark through a HUB or a mirrored port? If it's a hub make sure it's a true hub that sends all traffic to all ports, i've come across quite a few that are labeled hub but are actually switches.

Send me the db and i'll have a look

i have attached a link to the Samsung OS software.

I have linked 2 OS7070 via sip peering and sip calls are getting through but there is no invite captures on the wire shark.

That password doesn't work.
I wouldn't post passwords and db links in the open forum.

I have an OS7400 with a LIM card and have 2 x OS7070 IPPBXs ver 4.82 with my PC running wireshark all connected to the LIM card.The 2 OS7070 are connected to each other via SIP and if I run a trace, I am not picking any SIP traffic from the IPPBXs and portscans for the IPPBXs show port 5060 closed. SIP calls between the IPPBXs is there but wireshack captures no packets. Is this how Samsung IPPBX operate?

Not familiar with LIM cards but it sounds like they aren't a hub and don't support port mirroring so you will not see the SIP traffic.

The LIM card was released with the OS7200, it is a 16 port 10/100 dumb switch.
There is a PLIM which is the same as the LIM except PoE.
The LIM and PLIM cards can become managed switches with the addition of the WIM card.
The OS7400 introduced the GPLIM and GSIM and GSIM-T cards which are a 10/100/1000 version of the PLIM, and were also managed, the GSIM-T card has GBIC modules for connection of Fiber Optic.

I will have a look at your download shortley

I'm curious nameless, can you port mirror with those? I've only run across the 4 port POE cards that go on an MP10. Looks like in the US we only have (had) the PLIM, PLIM2, WIM, GSIMT, and the GPLIMT.
* Never mind. It's in a separate manual and I see the port mirroring, ours is called the 7200 Data Server.

Never heard of PLIM2, we never sold any of the modules.

A company my work purchased sold a few PLIM cards.

The problem is that the MP and MGI/OAS cards don't communicate via the back plane to the LIM cards, so you have to patch them into it or uplink them all to the customers switch.

I've never rtfm about the lim cards, that's only what i know from the 7200 install manual and talking to samsung.

The GSIM and GPLIM are routers as well I believe.

is there somewhere on the Officeserv ver 4.75 and higher where i can whitelist IP of PC running portscanner because what I see from attachments below is that port 5060 is closed.

Try setting your Comm Exclusive in SIP options to RESPOND.

You must set the private w/ public and put in the proper ip address information in 830. So that it will recognize incoming requests. Have you done this?
