Bad gateway on 3g over Publicmobile #1570

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 

1. Using free outbounb proxy like p.sippp.com:5900 (cause apparently 
publicmobile is using VOIP blocage
2. My Voip provider is voip.ms
3. My Cell phone provider is publicmobile

Using latest CSISIMPLE version Under android 2.3.4

I get Bad gateway when saving the account.

Any idea?

Thanks guys

Can you try to collect some logs (see HowToCollectLogs wiki page)?

Also, are you using the Advanced wizard to configure the account or some other 
wizard? (probably converted from a voipms wizard?)

Another point, some mobile carrier does not block on ports usage, but rather on 
packet types (it's deep packet inspection), if your carrier do that, using an 
outbound proxy that use clear transportation will probably not help. But that's 
good to try if you carrier does just a simple port restriction ;).

In the case of deep packet inspection stuff, you may need an encrypted 
transport such as tls (nightly builds has the feature) with a outbound proxy 
that supports TLS.

Disclamer : I don't encourage to try to break mobile carrier limitations if 
they clearly forbid doing a VoIP usage of their network in their contract 
terms. But sometime they do allow (or not forbid) but their network blocks 
things.

Hi and thanks for your fast reply.

I used the advenced wizard. So I think that they are using deep packet 
inspection :(
I would like to try with an outbound proxy that supports TLS. Do you know a 
trusted place where I can get a proxy that supports TLS?

I will install the night build and try. Thank's alot for your precious help :)

Unfortunately I don't know sip proxies only (I even discovered the p.sipp.com 
in this issue ;) ).

However, there is 2 sip providers I know well that allows to create free SIP 
accounts that allows TLS. (They also help me to test the TLS and secure 
features ;) )

One is https://create.tanstagi.net/ is down for now, but hopefully will be back 
soon.
The other is sip2sip : https://mdns.sipthor.net/register_sip_account.phtml (and 
http://wiki.sip2sip.info/wiki/WikiStart#Features)

Sip2sip also allows paid landline calls (tanstagi does not as far as I know).
I don't know if call rates are interesting for you however.
Maybe sip2sip allows proxying... I never tried.

Else there is maybe also other non SIP solution such as Fring that use a 
proprietary protocol to gateway sip behind. But well ... it's not SIP and it 
use some proprietary software and service :S... I would have prefer advising 
you some free as in speech solution. Maybe creating your own sip server would 
also be a solution, but it requires some IT skills :/
