obitalk 202 and cisco spa303 phone

[ciscoobi]

what is maximum number of cisco spa303 phones supported by one obitalk 202 device?
ITSP A is connected to google voice to provide incoming and outgoing calls.
ITSP B is connected to another voip provider for incoming and outgoing calls.

i can have 2 analog phones attached to obi202 device to be used with above providers.

ITSP C and D are unused at present.
how many cisco spa303 phones can be added to this configuration?

thank for the help.

I don't know the answer to your question. I also don't own a spa303.

What I can tell you is I just registered 3 softphones to ITSP D on my OBi200. Two were on Android phones and the other on a Windows 7 computer. I did not try any more devices. I did not try simultaneous calls. You should be able to register at least 6 spa303s on ITSP C & D. If the spa303 can call without registration then you can also use ITSP B for several more devices.

The OBi firmware was designed to route inbound calls to a max of 4 devices. This includes the phone ports. You can probably play games to get that up to 7 devices.

Have you registered one of your spa303's to the OBi202?

Given the low cost of system-on-a-chip computers like the Raspberry Pi, if you have the interest and technical know-how, it would make more sense to set up a PBX for those SIP phones than to fiddle with a OBi.  The OBi wasn't designed to be a PBX, so it becomes pretty complex to kludge it into that function.

yes.
i was able to connect one spa303 phone to ITSP C following the directions posted on obitalk forums. tested it for outgoing call on one line and it works.

this seems like an interesting link to setting up PBX using Raspberry Pi.

If you are going to use the OBi202 with multiple IP phones on one ITSP, you need to increase the Max Sessions parameter.
Voice Services -> SPx Service -> MaxSessions

Each simultaneous inbound or outbound call will use 1 session.

I didn't need all the options on IncrediblePBX, so I used Raspbx Beta version.
I found 2 minor bugs in the Beta version.
The Apply Config button turns red for no reason.
Just ignore it.
Problems with using zero as a dial pattern.
I could add the pattern, but if I subsequently tried adding or changing a pattern I would get an error.
I had to first delete the zero and then add it with the other changes.

Edit:
Max sessions also applies to the provider ITSP.
