I have and adtran 908e that we used until now to connect to out PRI T1 port on the phone system
so we have one side the WAN we got in a SIP trunk and on the other side a PRI
now we moved to hosted PBX system
our sonicwall does a very bad job with VoIP SIP NAT i am wondering if we can use the 908e just as router for the VOIP network, how is the NAT with the adtran
