    Very interesting discussion. Could you elaborate on your dialplan to make things work? It will be useful for us to learn.

    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.

Your config is my dream world.
Anyway, for incoming call forward (china->HK) GOIP has one call forward function, which you can call forward to OBIHAI's et263 SIP client. There is a multiple trunk mode, i have not success to enable it.
Pls let me know if you can.  So without trunk mode, you cannot call forward to multiple location (hk and abroad).
OBHHAI (HK) should able call forward to (LI).

Do not understand your outgoing statement, you mean you want to implement two way call forward?
you mean dial to IP01(PTSN), call forward to GOIP(IP01)?
or you just need to call OBI110(HK) then call forward to GOIP(phone), then from GOIP(call forward to you china number)?

Anyway,
have not test call forward in OBIHAI. you really remind me that it is a very simple way to call forward from china to HK>

    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).

To me, i need the CID in order to know who is calling
And cannot accept the delay with pstn->VOIP->VOIP->pstn, during office hours.

but i plan to use obihai call forward function after office hours.

    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.

yiucsw

you are lucky,
I just try the following call forward in this weekend.
1) BJ mobile call CN mobile (bj) ->(call forward)-> to landline (gz) -> obi(et263) -> hk(smv)-macau(smv). the quality is unacceptable
2) BJ mobile call CN mobile (bj) ->(call forward)-> to landline (gz) -> obi(et263) -> macau(smv). the quality is unacceptable at first 5 min, then better later.
3) BJ mobile call CN mobile (bj) -> (call forward) -> Macau (CDMA) the quality is good for first 5 min, bad for 10 sec, and repeat this frequency.

so i plan to buy an "GSM call forward to PSTN platform". Any suggestion?
Mobile (BJ mobile) -> platform -> Macau landline -> macau mobile.
which i can bypass all the route. and improve the sound quality.

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.

yiucsw

want to set up GOIP again. to forward call from beijing.
setup is fast. call forward to OBI SP2, then call forward to landline.
The sound quality is so so, need fine tune. (OBI SPX need time to stable the sound quality)

Then ask myself, why not directly call forward from GOIP to PSTN. change the call forward # et263 to 0+ china number. seem not convince and troublesome.

So ask ET263 helpdesk for set call forward number permanent for me.
XXXX3 is to call forward to my macau phone number. ...
so I only need to login goip and switch et263 number and incoming call will forward to different number.

But a plan is a plan, just after implement, i found the sound quality is bad.
Do not have energy to find out way. Any suggestion.
(The network quality may be bad, i may bring the GOIP to china for another test)

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...

yiucsw

i already install a very high DB antenna. 12 DB. for GSM connection.
Will try the local call forward function again.
Do you know if I can login to GOIP (trunk mode) and use OBIHAI as client?
or
what is the different of call forward mode in call setting and call divert.

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.

yiucsw

I try the configuration again but no luck.
GOIP (ET263) -> call forward -> OBI (ET263) -> call forward to landline. the delay is 2 sec. All in same lan segment. So you are luck for your config.

May be buy the ATCOM GSM gateway and try again

Do you have problem in the network set up? It seems 2 sec is too long.
