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.

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>

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.

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.

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)

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.

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

IP01 PSTN port is not working, and the OBI cannot have local access function as SPA3102, so i use ET263 call forward function. It may add additional delay.
I can clear hear the echo after i say "1 2 3 4".
That is why i plan to buy the ATCOM GSM/FXS/FXO device. what is local route.
What is your suggestion. ATCOM GSM gateway or build an ASTerisk server with GSM and PSTN module?

yiucsw

issue is that the only working model is GSM call forward to PSTN.
GOIP(GSM) -> GOIP(VOIP) -> OBI(VOIP) -> OBI(PSTN) is long path.
GSM Box -> Phone port -> PSTN(SPA(3102)).  is much shorter path. but delay inside SPA is still long.
so i guess ATCOM (GSM)-> ATCOM (PSTN) will be the shortest path. ?
do you know anyone has test the environment?
