SPA2102 connection to router

[boon]

Hi,

I'm considering getting a Linksys SPA2102 adaptor for the VOIP. I'm still confuse on the setup between SPA2102 and router as some of the information I get from other forum discussions are different. I tried to get it here but still cannot find one.

I would appreciate if someone would let me know which setup are correct and being used.

1) Phone line --> modem --> router (Linksys E3000) --> SPA2102 --> phone
or
2) Phone line --> modem --> SPA2102 --> router (Linksys E3000) --> phone

Thanks.

The other option could also work, but the SPA2102 is not a very good router. i would be happier if you switch the firmware to DD-WRT, but I suppose the default firmware will do.

Hi bridonca, thanks for your reply. Can I know which router is good comparing to SPA2102? Thanks again.

The SPA2102 is good enough as a SIP ATA, it is just that it's router is not very good. It is after all 6 year old technology. For the router, I find most will do the job, it is just that a lot of them have awful firmware. So, if you can get a router that can also be flashed with a decent 3rd party open source firmware such as DD-WRT, that is a good router.

I'm ok with SPA2102 used as a SIP ATA as I already have Linksys E3000 as a router. Reason of using SPA2102 is when I'm travelling to another place without my E3000. Can I flash SPA2102 with DD-WRT? Can't find the firmware from DD-WRT site.

No, you generally cannot flash third party firmware on combo units, just certain routers. The E3000 can be flashed with DD-WRT, though I believe the stock firmware is already pretty good. The stock router firmware that comes with the SPA2102 should do if you are in a pinch, it is just that the configuration options are more limited if something is not working the way it should.

noted. I'll go for the SPA2102. Thank you so much for all the info. bridonca.
