Sorry that I have to type it in English.
I can not always call my VOIP phone. If I just made a call from Line 1, then I would probably be able to call in. If I dial # to use Line 2, then I may lost the capability to call in. Here are some basic settings:
ATA: SPA1001.
Phone Services:
(1) Sigate.com,free service with a free phone number, 724-xxx-xxxx.
(2) Rynga.com, paid service for International calls.
ATA Configuaration:
Line 1: this is the default one, entered Sipgate's settings;
Line 2: entered Rynga's settings. Dial # first when call out;
With above settings, I call make domestic calls from either line, and call China using Line 2. When call from Line 1, the receiver can see my phone number, 724-xxx-xxxx. However, if calls made from Line 2, then the receiver only see a random number, and it changes every time I call. When taht happens, I'll have trouble to call in to my VOIP phone.
Since the Line 1 was DEFAULT, I thought it should automatically respond the calls from outside. Do I need to change anything to get it working steadily?
