183 - Session progress

[ysam]

Any chance of implementing this?

When phone receives an 183 session progress it just refuses to do anything else.

The only way for call establishment is for the phone to either receive a 180-ringing msg or nothing (and 200 - OK) after the invite.

Any workarounds around the block would be also appreciated.

It's so pity for thouse nifty N-series phones.

It's a shame that Nokia phones are not fully SIP compliant till now.
I wonder why is it not important to support session progress 183?
