I sent an Obi110 to a friend in HK (calling it ObiHK). Prior to sending, I updated the PHONE to use PSTN as Primaryline and LINE with the following:
Ring Dection settings specifically for HK Telco Standards:
Physical Interface --> LINE port --> Ring Detection
Ring Frequency Min: 10
Ring Frequency Max: 100
Ring Validation Time: 256 ms
Ring Indication Delay: 512 ms ( same to default )
Ring Timeout: 640 ms
Ring Threshold: 13.5-16.5 Vrms
Ringer Impedance: High (Normal) ( same to default )
PCCW is their landline carrier.
After connecting the Obi to their network, connecting a phone and LINE port, the lights on Obi corresponding to Internet, Phone and Line are solid green. Call quality from ObiHK to other Obi's and one stage calling to other Obi's via their respective PSTN is very clear. However using the Phone connected to ObiHK to dial a local HK number, I'm told there is a lot of static, choppiness. One stage dialing from my US Obi to ObiHK does not work. When I dial into ObiHK's AA and press # to test the PSTN, there is no tone. It appears ObiHK is not detecting PCCW? Please help. Thank you.
