I did a little investigation into my one-way voice issue, and noticed
that if I don't do voice-menus (i.e. where the Asterisk box itself

INVITE once a handset picks up) then I get two-way voice (i.e. with
sending the call directly to the phone). (In this topology, my
Asterisk box is also my firewall/NATting router...)
If I enable the voice menus in the inbound dialplan, however, it can
hear the voice menus, but not the called-party when they pick up
their phone (extension).
So someone (either the SIP conntrack module on the Asterisk border
firewall or else the SBC at the ILEC) is failing to look into the 2nd
INVITE (i.e. we're not rewriting it properly as it goes by, or the
SBC is failing to see it).
What module options are you using for the SIP helper and how is call
setup in asterisk configured (directrtpsetup, canreinvite, ...)?
For the PSTN's switch:
CanReinvite : Yes
I vaguely recall some problem in the implementation of this feature,
something with missing bridging of the RTP streams that was still
necessary under some circumstances. Might be worth to try turning
it off.
What about the module options?
