Hi All,
Q: Anybody solved problem T.38 Relay AudioCodes to CS1000E?
Audiocodes mp-112 ver.5.4
CS1000E ver.5.5,
Registrar IP = a.b.c.12 (NRS)
SIP Proxy IP = a.b.c.10 (CS virtual IP)
MediaGateway IP = a.b.c.15
I can sent fax from Audiocodes connect fax machine outside, but cannot sent fax oposite direction. What i discover:
1. SIP session setup works fine (INVITE)
2. When to sides discover that is the FAX transmition, PROXY
is sending ifnromation to Audiocodes that RTP session
for T.38 transmission should be started with IP of MGC
a.b.c.15
3. But Audiocodes doesn't Accept this redirection with
Error Message T.38IP Address not Allowed.
What is intresting is that as in oposite direction FAX
transmistion works fine including T.38/RTP transmition to
a.b.c.15 which is the MGC.
Not Fax calls works fine in both directions.
Well Nortel CS1000E IP architecture is not easy.
