aloysius,
Let me see if I understand the question
*67 blocks caller ID one time when dialling from the OBi110 using voip.
You wish to send *67# to your telco PSTN line to stop the telco sending out your Caller ID.
If I understand correctly, then there are several possible answers.
Leave the OBi *67 as it is. When dialling via your telco PSTN line start with #, which bridges the phone port to the line port, then dial out using *67# followed by the number.
Another answer is to change the number in OBi Star Code 5 position to different digits, maybe *66, and use that for voip calls. Then add *67#xx. to the beginning of your Line Port DigitMap , so
(xxxxxxxS4|1xxxxxxxxxx|xx.)
Change to:
(*67#xx.|xxxxxxxS4|1xxxxxxxxxx|xx.)
Now, assuming that Phone Port PrimaryLine is PSTN, then any call starting *67# will go to the telco. The DigitMap can be refined if the calls starting with *67# are of a definite number of digits.
I hope I got the question right!!
