cme 3.3

[nettuno8_20111]

i have a spa122ata i have a problem i can't get it to work with a router 2600 CME 3.3 registers to the cme but does not forward calls and does not receive them from other ip phones, the problem is that the sip configuration of the CME 3.3 is different from a CME 7.0 I have CME 12.0

That router is end of everything since a very long time, so I don’t think that you would be able to use it for what you intend as the version of CME that is part of IOS on this platform would be very old. Apart from that it’s not really clear, not to me anyway, what version of CME that you have as you mention a few different versions. Could you please clarify?
