N95, SIP blocked over 3G (HSDPA)

What is the simplest way to tunnel SIP traffic on a N95 Symbian device?
Is there an SSH client that would allow tunneling? Some simpler way?
(by simpler I mean not requiring me to install 3rd party software.)

I would guess that this is port blocking?
If so, there are some voip providers that operate on alternative
ports.
I think pbxes.com do this and Voxalot were planning to do it but I
don't know if it went ahead. There may be others. You might be better
posting on
uk.telecom.voip

Or deep packet inspection, in which case...

....would not make any difference

Unless you tunnel and encrypt. They can't inspect encrypted packets, and
if you did it over non voip port like the UDP OpenVPN ports you might
get away with it? ( I will investigate this by using my phone as a modem
before worrying about how to solve it within Symbian) However I've now
decided to just pay to upgrade my Web n Walk to Web n Walk MAX where
there is apparently no restriction on using VoIP over HSDPA. It's only
like £5 difference a month.
