Alternative telephony (or VOIP is not only SKYPE)!

I live in Moscow, in the light of the fact that they will soon again increase the unlimited tariff once again decided to look for alternatives (good SIP phone at home too) ...

At one time - free unlimited Moscow was consistent: in Sipnet, Corbin, Comtube ...

While came up with this option:
for incoming calls leave MGTS ~ 130 rubles
for outgoing calls Voip operator Globe7 ~ 150r ($ 5)
')
Total: the whole "city" telephony costs 300 rubles, while in the bonus, we receive calls to landlines in St. Petersburg, Canada ... and a number of countries (to which there is no one to call)
For comparison: the current unlimited MGTS costs 380 rubles, after the increase it will be 419 rubles
Can someone suggest other SIP alternatives?
And the options for using iron SIP equipment is preferable.
Yes, I forgot ... you can certainly use countless Betamax clones. But maybe there are some new names for me?

PS Skype with its tariff plans, please do not offer!
