The receiving T42G never gets an "Alert-Info:info=alert-autoanswer...etc" because the originating phone isn't sending it out. The invite is not coming out of the T42g with the "Alert-Info:info=alert-autoanswer." We have the T42Gs set up exactly like the T48gs. The T48Gs are working; however, the T42Gs are not.

Hi,

So, in your scenario, T42G and T48G are both receiving phones, when you test with the same originating phone, T48G works fine, but T42G didn't, am I right?

Please kindly provide the trace files to me, if you could provide the trace files of T48G, that would be much helpful.
a. Level 6 syslog
b. PCAP trace
c. Config.bin
You can get the guide from this link to see how to export the issue data(trace files):
