So which is better Cisco SPA2102 or Obi202? Almost identical
Tuan:
I tried to do a search for spa2102, but didn't get result I wanted. On the outside, they look identical.
I heard about the Cisco's echo issues, but not sure if they fixed it. Obi202 seems to be the favorite.
Tuan:
I actually got both units and tested them out. The result is that the Linksys SPA2102 has faster connection speed. I wonder if the Linksys has a faster chip.
Here's the test:
With both units on the same network (using ATT Uverse 2wire modem with built-in router) and both using voip.ms (same codec g711u), the Linksys SPA2102 seems to respond faster at reaching the destination after dialing the same test 888 toll free number. I timed the connection after dialing the last digit to the time the Virtual Receptionist picks up on the other end. I dial 10 times each for the Obi202 and the Linksys SPA2102 to make sure the results are consistent. The Obi202 (firmware 3.0.1 build 3932) takes about 5 seconds, whereas the SPA2102 takes about 2-3 seconds.
I wonder if Obi202's new firmware would reduce the connection time.
Mango:
I consider the OBi202 the upgrade of the SPA2102. The SPA2102 is now out of production. You may be interested to know that some of the staff from Sipura (designers of the SPA2102) now work for Obihai.
The OBi202 has a lot of advantages over the SPA2102. In particular the SPA's router is slow by today's standards - its maximum speed is about 7.5 Mbit/sec. The OBi202's call routing features are also much more powerful; for example you can register to up to four service providers (including Google Voice) and route incoming calls any way you like. You mar also set up many voice gateways for routing outbound calls. The OBi202 also allows you to use devices such as the OBiBT, OBiWiFi, and OBiLINE.
You're correct that some users reported echo when using an older PAP/SPA device.
The only real advantage the older PAP/SPA devices have is a configurable jitter buffer. This may be useful if you want to use a monitored alarm system, point-of-sale credit card processor, or any other device that sends data over the phone line.
As for Tuan's test, the results are probably related to the dial plan. Wireshark would tell you for sure, if you care to examine what is going on in more detail.
carl:
I never experienced any problems with connection speed of Obi 202 or Obi 100. Fast.
Tuan:
Dial Plan of the Obi:
(1xxxxxxxxxx|<1559>[2-9]xxxxxx|<1>[2-9]xxxxxxxxx|011xx.|xx.|*xx.|(Mipd)|[^*]@@.)
Would this cause any delay?
I agree with Mango that the Obi has more settings, but my main concern is the quality of call. Right now, the spa2102 is giving me the lower latency compared to the Obi. If you guys are not having issues, I have to reset my Obi to factory to give it another shot.
Carl: How fast is fast? Can you give me the number of seconds that the other side rings?
