I have been reading this site for a couple of years now. Thanks for all the great info. Ward.

Since I don’t have my asterisk box running at the moment I tried to get the phone to register directly with one of my VoIP providers, so far without success. I’ll be out of country for awhile beginning this week and I was hoping to be able to make SIP calls while away.

Thanks for the article.

Thus i believe it should handle. but if not i would be able to use fring . correct me if im wrong

[WM: No SIP client is listed. You could use Fring but it’s not as flexible.]

Do you know if the E72 will have the same voip client built in . it seems to say it supports voip over wifi on the phone specs.

Any help will be appreciated ..

[WM: Not sure. Suffice it to say Nokia hasn’t released a new phone with SIP stack and SIP client in more than a year so I wouldn’t hold my breath. They appear to have killed that functionality permanently in order to gain favor with some of the cellphone providers (such as AT&T).]

There is no need to upgrade to the latest 300 series firmware as it prevents rooting your telephone to allow homebrew applications to be installed. The 200 series is fine. Also Nokia no longer allows rolling back to an earlier update so be very careful.

A list of Nokia phones confirmed to work with the built-in SIP client include: E51, E60, E61, E61i, E63, E65, E66, E70, E71, E90, N82, N95. There may be more. I’d also double check those phones work because non-unlocked branded phones may have the SIP features disabled. There is a way to change the product code and reflash Nokia phones to remove the restrictions but I’ve only documented how to do this on my blog with the E61. Your mileage may vary with other models.

Lastly, I reviewed the E71x (available through AT&T) on my blog through the Nokia WOMWorld program and I would definitely avoid it at all costs if you want to do VoIP without an app like Fring. If you don’t mind using Fring then you can do everything in this article.

I’ve seen it in the $100-$140 range at howard forums ( when you can find it ). Quite a bargain for the VoIP inclined since that’s cheaper than a lot of less featured sip devices.

after rooting it and loading a nice custom rom
from cyanogen I have a free wifi/bluetooth tether
I can store my apps on my sd card and even with out
rooting it I was able to place calls on voip servers

I have tried various setup on my piaf server but I in the end just put my android in my main ring group and now I hardly ever use my phone at home

[WM: Correct. VoIP is non-existent… but AT&T has nothing against VoIP. 🙂 ]

Honestly if you are cost sensitive it’s a great alternative to the e71 since it’s a good $100 savings. Some recent, but expired, deals had the e63 priced into the $160 range is a real steal for these VoIP features.

I can justify $180 ( actually less if you get a deal ) for a phone, but close to $300 just seems like too much for my taste. It’s really just unfortunate the android phones have not really developed.

STUN can be fixed ( if needed ) on the e63/e71 with the utility named ( SIP_VoIP_Settings_v1_2_en.SIS ) which allows you to configure the hidden settings. Many providers don’t need the fix because they presume that the user is behind NAT. I find that configuring STUN helps in some of the edge cases like double NAT-ing.

I have paired up the VoIP with T-Mobile TOGO, but I think I’m going to try AT&T as well since the coverage for T-Mo is just too poor, even as a backup. For the VoIP side my setup includes SipGate/Sipsorcery/Google Voice as my primary and several other backup VoIP provider that I can turn on and off as needed.

Any compelling reason to go with the E71 over the E63, besides color??

Thanks as always for your inspiring blog entries, Ward!!

[WM: I think I’ve read that there’s no GPS in the E63, slower processor, less RAM, etc.]

I rooted mine and put sipdroid on there. It works fantastically – plus with the wifi tether app, i get a mobile 3g hotspot for no extra cost.

[WM: The phone connects to WiFi networks that you choose, not every WiFi network that sends out a signal. We were suggesting a method for keeping your phone at optimum performance. It’s not going to crash after you pass by a dozen WiFi networks. 🙄 ]

Uhm…this seems like a big problem and headache. With the prevalence of wifi, especially in dense urban areas, I could probably encounter this issue just driving to work through my large city’s downtown.

[WM: Not a problem if you don’t reset it. We go through WiFi-infested areas all the time. 🙂 ]

[WM: With regard to STUN, see the comment below. We’ve never had a NAT or one-way audio issue with either the original phone firmware or the newer release… at least using dLink gaming routers. YMMV!]

I bought $100 (1,000 minutes) worth of credit on a T-Mobile prepaid SIM, which they allow to last up to a year. A year of cell phone service for less than $9 a month? Yes, please!

On the server-side, I set up an extension for the phone’s VoIP capability and routed my DIDs to it. Then, instead of setting up separate extensions for ringing the SIM card, I added Follow Me settings for the first extension. I told the server to begin calling my cell number when my extension received calls. I measured the amount of time for an incoming call to begin ringing the SIM, added a few seconds and set that as the ring time of my extension. Now I have a paging system at no extra charge! Neither my outgoing VoIP provider nor T-Mobile charge for a phone ringing. For the off-chance that my phone had no signal or was turned off, I activated the "Confirm Calls" option in the Follow Me settings so the server wouldn’t start leaving costly three-minute messages anytime someone called.

Thanks for the inspiration, Ward! This phone setup has been working great for me all this year. I figured I almost always have WiFi access and when I don’t, I’m probably somewhere I don’t want to be taking calls anyhow. But if I do happen to care, I can see that I missed a call, simple as that. New telephony: it’s so… beautiful!

[WM: Yeah, you’ll need T-Mobile or AT&T service in the U.S. unless you want to use a prepaid card from AirVoice or O2 Wireless.]
