Hello, all.
I have NEC DSX80s (version 3.14) installed at separate sites with an 8 license VOIP DB installed in each. At each site, I have installed a Linksys PAP2T that is connected to CO lines 7 and 8. Both PAP2Ts have registered successfully with the remote sites DSX80. Interoffice communication works as it should if a user picks up line 7/8 and dials the 3 digit extension of a remote user. However, if a user dials 401 or 402 (the local VOIP extensions) from intercom, the remote DSX80 will ring in on line 7/8, but the caller can't hear the remote site or vice-versa. This happens in both sites.
Perfect interoffice calling from the ATA to the remote VOIPDB, but not from the VOIPDB to the remote ATA.
Summary of setup
NEC DSX80 (192.168.112.7)-------Router(192.168.112.254)~~~~P2P T1~~~~Router(192.168.111.254)-----Linksys PAP2T(192.168.111.8) to CO Lines 7/8 on NEC DSX80 (192.168.111.7)
and

Any ideas?

Did you open the needed RTP ports on each router?

No voice usually means no UDP packets getting through.
