[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!

Can your GOIP connect to the asterisk server and work well?

I understand ET263 helps a lot in quality but for redundancy,you may consider to add a sip connection to asterisk server directly.

ckleea

For Asterisk server, will you also consider to add the Obiapps to it to increase the flexibility

    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?

Buy our model or the one from Magic -pro. It all depends if you need to install a PCI TDM 400P card. If you do not need, go for a slim D525 from Magic-pro. Also get a SSD will be excellent for the operation.

For me, I use 2.5" HD, it does generate some heat but mine have been on for weeks.

    Can you elaborate a bit for GOIP? Is it a ippbx similar to IP01?

Qnewbie

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

Have you considered the trunk group of OBi device?

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

    I see what GOIP likes. Combo H323 + SIP. It limits your connection. I think if you have an IPO1 in china will help you a lot.

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).

You may use ET263 on your GOIP. Whenever your relative in Mainland China calls your mobile number in GOIP, it formware to call another ET263 account to improve the voice quality for over 15 minutes chat.

I have nearly the same configuration as you but finally i give up.
I have test GOIP with use ET263 and/or IP01. and find the following problem mostly is introduced by GOIP.
1) GOIP introduce a lot of delay.
2) GOIP also do not identify itself in roaming/local call condition.
3) GOIP is not stable and will hang(need to add a timer to reboot)
4) GOIP will discharge all SMS except GOIP SMS control message.
5) GOIP cannot call forward to multiple number.

The way i handle it is two fold 1) outgoing and 2) incoming
1) outgoing - use ET263 as outgoing and apply your mobile # is CID. RMB$0.08 per minute with excellence sound quality is much better than mobile call.
2) incoming -
i) the best solution is call forward # (一号通). but now it  cannot forward to HK # now. otherwise it is the best way. (1.5 per minute to call hk/macau)
ii) add a fix line and obi/spa, then mobile number is call forward to fix line. 20/month for fix line. but you loss the CID number
iii) buy an hk/mainland SIM card and call forward your mobile phone to this new HK issued sim. then in HK call forward to your HK fix line. 0.69/min + 0.2-0.5 call forward price. + monthly charge.
iv) activate the secretary service. and call back when you receive SMS message.

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).
