That's a pretty old version.  The latest one on the site is:

http://splurge.peoples-wireless.com/ipkg/asterisk-cvs_1.0.32_mipsel.ipk

Which is CVS-head from just a couple of weeks ago.

Are the phones which are trying to talk located on networks using NAT?

That symptom is a classic one for SIP phones that are behind NAT.  There 
are a variety of fixes, check out the Wiki at www.voip-info.org
