I tested with a Public SIP server here in Australia.

The system was an OS7200 with a MCP, a MGI card, and a DLI card. The WIM is not required.

The ITSP gave me the following information:

A Public SIP Phone Number
The SIP Server IP address
The SIP Server Domain name
A User account number (same as phone number)
A user account password.

These were entered in the OS7200 MMC 837 as follows:

SIP Server enable: Enabled
Server IP Address: XXX.XXX.XXX.XXX
SIP server port: 5060
Allow Gateway IP Check: Disable
regist T-GW Number: SIP Phone number
GW Domain name: sip.XXXXX.com.au
GW User ID: SIP Account name
Register PSW: SIP Password

There is a field called Service vendor, this seems to refer to the type of Softswitch used by the ITSP. I used trail and error to get a setting that worked for me.

All other setting were default

I used an IP packet trace SW package to check the SIP messages between the 7200 and the SIP server, and when it registered I could see the registration message.

Best of luck

let me know how you go.

Thanks ctiuser! I have one of my OS100 systems already running 2.63 and can see all the settings you ahve mentioned here, so it is time to have a play I think and see if I can get this working... will post back my results.

I'm waiting for my Samsung supplier to update my main OS500 to 2.63, it is currently running 2.60 and is missing the auth SIP settings... hopefully will have this done in a few days.

Question for you though, how did the system respond to having the SIP settings set? What I mean is did you have to setup trunks to access the SIP server? Can you have multiple calls going on at the same time via the SIP server? I'm just curious what other work is involved in getting this working or is it all on MMC837?

Thank you for detailed information, i will let you know.

The SIP trunks are trunks, similar to Analogue, ISDN, or H323

Therefore all the usual Samsung trunk programming applies. MMC 406, MMC 714, LCR rules etc.

By default SIP trunks are grouped in group 805, and are numbered 8501, 8502, etc.

The number of multiple calls allowed per registered account is determined by the ITSP.

In my previous post, i forgot to mention that the ITSP provided SIP phone number has to be mapped in MMC 323 "Send CLIP table" and MMC 714 "DID table".

This is required for the OS7200 to send and receive a Valid CLI number to / from the ITSP.

Thanks! Will try this with my system next week and report back.

Aero - have you had any luck given this new info? What type of OfficeServ system are you running?

Yep already got there, I see how that can work but I have chosen to register the Asterisk server with the ITSP and register the OfficeServ 7400 to the Asterisk box. It works well the only other change was DTMF type in MMC835 needs to be Inband(RFC2833) or Asterisk just hangs. Mail-call on Asterisk is brilliant for playing my emails when iam on the road.

Hi there,
i tired to setup, but until now not working.
My provider accept all traffic from src IP to Destination, so no Authentification needed. But the provider requests, that the call should be sent in a format 00+cc+nsn@ip:5060

Does any some know where to setup this format ?1?

Good news ctiuser

So I take it you have been doing some testing how has it been performing?

aero, i'm quoting for a customer who has asked if the switch is sip ready.

I'm trying it out on our inhouse 7200.

Do I require this "Asterisk" box or can I just use the settings as ctiuser has written out?
