[Help]Deployment Preparation

Qnewbie

This post looks like cross different topics. Just pick this as Obi110 is unavailable for me currently.

I am planing to set up system for voice communication between HK, Mainland, and aboard.
Main system is located aboard with 1 IP01, 1 Obi110. Mainland China(1 GOIP) and HK(1 Obi110) is used as two branches.

Wanted:
Redundancy: one peer is down, other two peers can communicate with each other. The only exemption is mainland China, as GOIP or ET263 is down, then every thing from/to mainland is down. It can only be compensated by VSP.

Preliminary planing:

Help is needed for:
1. Call route for Obi110@HK.
2. Better deployment.

TIA!

    The direct connection with GOIP and Asterisk is the VOIP traffic blocking in mainland China. I can only put GOIP there and cannot add one more router.

    It would if the Asterisk is built with PC. Any recommendation for the passive cooling ATOM D525 PC?

Qnewbie

No, it likes like combo of GSM box and single FXO gateway.

    I am considering which VSP can be used(better if verified) as trunk group: pennytel, iptel, sip2sip, and Betamax.

Qnewbie

The option of adding router or other stuff is limited. That's why I choose GOIP(mainly used as hotline).

Another route from mainland China goes thru callback with 角色 C-hing's help(not implemented fully until I visit mainland China).

Qnewbie

Thanks yiucsw C-hing!

Currently I use GOIP+IP01. The combination does work as GOIP and IP01 in the same LAN. I don't experience the delay problem(maybe the delay between GOIP&IP01 is small enough?) I use GOIP as DID, just for inbound calls.

The GOIP, as planed, is to used as hotline(飛綫). As incoming calls (only trusted numbers) will be forwarded to OBi110(HK), which in turn, either to phone@HK or to IP01(call route@Obi110). The outgoing calls are placed@IP01 with second stage dialing(GOIP => Obi110@HK=> IP01 => PSTN). Delay is the worst case. Better to launch callback@IP01 in stead The call from HK/Aboard is just forward to a mobile number.

In my case, it is a more simple task for GOIP:
1) GOIP introduce a lot of delay.  <= It would be severe!
2) GOIP also do not identify itself in roaming/local call condition. <= Hotline&fixed place, I think it would be OK.
3) GOIP is not stable and will hang(need to add a timer to reboot) <= It can be rebooted once a day with its own function.
4) GOIP will discharge all SMS except GOIP SMS control message. <= Pure voice applications.
5) GOIP cannot call forward to multiple number. <= It forwards only to one number.

I think the GOIP is not so bad for me(I might only place 1 piece of hardware in Mainland).

    I don't get Obi110 in my hand. So the detailed call route@HK would be "Help"

There is not fancy stuff for the dialplan. It should be a simple AA like "to call HK, press 1, to call other destinattion, press 2" and hopefully, ET263 and Obi110 could handle this.

On IP01, the dialplan is quit simple. Just treat OBi110@HK as a trunk. Inbound calls are directed to IVR. Outbound call is placed to OBi110.

    Thanks again!

I am not sure that this config would work.

The two way call forward is not a general one. Call is just forward and backward to a fixed mobile number:
Mobile 1380013800 <=> GOIP <=> ET263 <=> Obi <=> IP01 <=> Other destination

The only thing that works is GOIP acts as DID for mobile phone. The GOIP register to IP01 within the same LAN and second stage dialing works. But I am not sure that the second stage dialing works from mobile to IP01. The outgoing call is mobile to other destination THRU ALL the way.

Qnewbie

In GOIP, there is hotline function.

You can forward to ET263 number(call initiates from mobile) or to mobile number(call from ET263 number).

    During the office hour, you might use callback function(it would be convenient that Asterisk is implemented with PC).

For me, the CID is "known"(restricted by trust list in GOIP). Hence, I prefer this config

There is CID call forwarding function in GOIP, I haven't tested it. If you use GOIP+IP01(direct connection), you might test it.

Qnewbie

Sounds deployment of company branches.

If I were you, I prefer place DD-WRT/OPENWRT routers with openvpn for connections. Each one could possible with asterisk, or connect to asterisk at HK(or place with redundant internet connections). With this deployment, it might solve the delay and voice quality problem.

Qnewbie

The internet connection is a must for VOIP. If the bandwidth cannot be guaranteed, all other attempts are in vain.

GOIP needs a better antenna to improve the voice quality(GSM problem?).

You might to replace GOIP with GSM box+SPA3000. Still, GOIP(anttena)+VPN would be my dream...

Qnewbie

I am not sure.

If you are using GOIP from DBL. There is remote control. It might help.

"Call Diversion lets you divert your calls to almost any phone, including your mobile. Call Diversion can also divert calls while your phone line is in use." Call forward is just transfer your call, not matter what it is. Actually I don't see any difference for GOIP.

Qnewbie

I have to fine tuned IP01's FXO port. Maybe you need to do that too.

I think "ASK before BUY" is the best you can get right now.

I still need to buy one GOIP. But US$199 is ......

GSM box+SPA3000/SPA3102 has less delay than GOIP, which is the test result from YHChing.
