[Question] is it possible direct call number calling to outside?

Hi. I'm a junior telepresence engineer, and I wish to know it is possible to direct calling with only numbering.

I'm using several SX20 and ISDN G/W for connecting to phones.

I set ISDN G/W 3241 coneect to SX20 when rings with certain phone number by 'Dial Plan configure'

So, if I call 1234-1234 from phone, then my SX20 answers it.

but, outbound call is not simple, I don't know how to setting on dial plan.

of course, it's possible to call like this 2932483@10.200.244.200, then the phone starts ringing.

(10.200.244.200 is ISDN G/W IP) (2932483 is PSTN phone in outside)

but call with only number 2932483, it doesn't work.

ISDN G/W is gatekeeper itself with 127.0.0.1 registered and SX20 is H.323 Gatekeeper call mode. so, I think only numbers also possible to call to outside.

I tried and changed several settings, but never worked. Am I wrong? or need more devices like VCS?

I wish someone help me.

thanks for reading. English is not my mother tounge, sorry for inconvenience.

Hi Jinsung.  Good morning.  Sounds like you may need IP to ISDN dial plan rule on ISDN GW.  If you navigate to dial plan rule page and click IP to ISDN, do you have a dial plan rule listed?

If SX20, is registered to internal gatekeeper on ISDN GW, you have to create the IP to ISDN dial plan rule to have the call sent as you suggested.  So if you want to make voice call out your isdn GW, set dial plan rule to show:

The snapshot below is from 2.2 GW which was released a few weeks ago:

70 is the service prefix that I'm using for audio only calls.  Under action, i require a 9 to get outside line so I add it to the string so the user doesn't have to.  70(D*), so when i call 702932483 for audio only call, the 70 is registered to internal GK on ISDN GW and the call is sent to the GW side.  The call is then place out the ISDN network as 92932483. 

Once you've created the dial plan rule, you have to register the 70 to the gatekeeper.  Navigate to the H323 page on ISDN Gateway and input the 70 to the dial plan rule under "Dial Plan Prefixes"

At the bottom you should see the status as this GW is also using its onboard GK as well.

If you navigate to the gatekeeper page, you can then also verify the prefix is registered as well.

Place the call out when SX20 is registered using (Service Prefix)(ISDN Number) like 702932483 and see if the call goes like you would like it to. 

Hope this helps.

Hi Patrick,

Very thorough answer my friend! Great work +5

Cheers!

yesterday, I set the configure as same your advice.

yes, it worked well from inside condec to outside call to mobile phone through the ISDN G/W.

ISDN to IP and IP to ISDN is perfectly well worked. but, when I set like this, the new issue that IP to IP call never worked

has happend.

we have used standalone mode SX20 to connect other users, but for IP to ISDN call we should change the H.323

mode from Direct to Gatekeeper at each SX20. when we call ther others, it looks calling and signalling,

but opposite side never got any signal.

the H.323 gate keeper is ISDN G/W internal gate keeper, and it looks registed well.

we called with IP, ID@IP, E.164 Number but, the opposite side never got any signals.

if we have VCS then we can control by the dial plan menu but, we only have ISDN G/W and MCU 4501.

and I saw the menu IP to ISDN and ISDN to IP in ISDN G/W 3241, but I couldn't see IP to IP or ISDN to ISDN dial plan.

I thought ISDN G/W GateKeeper or MCU GateKeeper can forward the h.323 video call to other connected devices.

am I wrong? and is there any way to be enabled IP to ISDN, IP to IP and ISDN to IP call all?
