I've spent three hours on this today and have been forced to put this aside..
We have a VOIP line for home. Works flawlessly.
That's handled by our Huawei B593 modem. Plug the phone into the back of that, put the SIP settings in, works great.
That can only handle a single VOIP circuit, so I bought an "ObiTalk" box to handle a second VOIP connection for my home office. That box plugs into the Ethernet port on the above Huawei modem and registered for a second VOIP account with the same provider, Sipgate.
I thought that the two might "interfere" with each other, but after looking through help guides and Sipgate's instructions absolutely nothing will get this to work.
The key seems to lie with the "User Agent Port" and the port ranges. Both the Huawei and the ObiTalk boxes want a range of ports specified.
For VOIP #1, the working line, the Huawei has the User Agent Port set to 5060. The default port range - you only specify a start number - begins at 50000.
For VOIP #2 I've tried various options and workarounds:
- Specifying a STUN server
- Setting a range of VOIP #1 to 50160 - 50176 with User Agent Port of 50160 - this line still works fine then, and for VOIP #2 50260 - 50276, User Agent Port 50260
- Fixing the IP address of the VOIP #2 box in the modem
- Port forwarding in the modem
The ObiTalk box, VOIP #2 won't even register. The error is server timeout - no response.
Oddly enough if I take that box and plug it into our router which VPN's everything, it *will* register. Though calls don't work.
Though I don't want it behind the VPN as that adds latency hence the reason for plugging it into the "outer" modem instead.
None of the configurations I have tried will work. I suspect I'm missing something quite simple, but all the above tries have been based on what I have read and everything has failed.
Any ideas..
