Is Asterisk 1.4 compatible with 1.8.7 ?

After upgrading one of my server to asterisk 1.8.7.2 (the older is running 1.4.39)

When I try to dialin on asterisk-1.4.39 I get an error:
NOTICE[2414]: chan_iax2.c:9541 socket_process: Rejected connect attempt from 192.168.141.8, requested/capability 0×2/0×703 incompatible with our
capability 0xc.
NOTICE[2417]: chan_iax2.c:9541 socket_process: Rejected connect attempt from 192.168.141.8, requested/capability 0×2/0×703
incompatible with our capability 0xc.

On asterisk-1.8.7 I get:
WARNING[4277]: chan_iax2.c:10666 socket_process: Call rejected by 192.168.141.1: Unable to negotiate codec

I’m using ulaw / alaw code; why don’t they communicate?

iax.conf (1.4.39)
[home_server]
disallow=all
allow=ulaw
allow=alaw

iax.conf (1.8.7)
[clinic_server]
disallow=all
