Huawei B260 - Voip

drunkmonkey

Using this device http://www.huaweidevice.com/worldwide/productFeatures.do?pinfoId=2528&treeId=3155&directoryId=2741 can you plug an ip phone straight into it, what i'm thinking it moving an eircom number I want to keep to blueface and using the 3G sim as the internet connection for calls. So for 9.99pm (1GB=2000 Voip Minutes?) i'd have unlimited national calls.

Is there a better way to do it over 3G using a different device?

3G isn't really suitable.

I'd use a Grandstream 286 on a dovado or Linksys/Cisco 3G router. Dovado actually had a model with phone port built in.

Then you plug in ANY phone inc a DECT. If you have an actual IP phone (rubbish compared to an ATA builtin to a modem or Grandstream 286), then all you need is ethernet or WiFi, depending which kind of IP phone it is. I've used the Nokia E65 (SIP) as an IP phone via WiFi on WRT54G3G wifi connected to mobile and/or cable.

Reliability and quality via 3G was poor. Perfect over Fixed Wireless, Cable, ethernet and even Digiweb mobile.

If you have NAT/Router rather than the IP phone using a public IP then you need all kinds of magic settings (which Blueface supports) STUN, VOIP proxies etc.

It's unlikely that incoming VOIP calls work on a 3 Network unless you are online.

Hi,

Just trying to understand what it was meant by... "It's unlikely that incoming VOIP calls work on a 3 Network unless you are online."

thanks a million.

General problem for Mobile (as it's not always on):
How would the SIP server of Blueface or whoever know what IP address to call?
One solution to dynamic IP is "presence". But that assumes you are online.

You CAN NOT keep a 3G/HSPA modem connected all the time. The operator or traffic in cell will force disconnects.

3 uses a transparent proxy (other mobile APNs may also)
In this case there may be NAT and shared IP. Incoming calls can't route easily. There are ways round it, but usually on internal office NAT using ICE, STUN etc..

For similar reasons, hosting VPN, IMAP, SMTP, VNC, SNMP remote control or VLC at home "shared" via a 3G modem is unlikely to work. There is nothing for the the remote client to connect to unless your home/office end does dialup on 3G and "registers" with dyndns. Even then it won't work with transparent Proxy/NAT and an IP shared among many users at the same time.

All these things work on real broadband and if used remotely by just a couple of people the traffic is low and doesn't contravene the "spirit" of not running a server clause in most T&C.
