Hi all, i have a TMG beta3 and an appliance Digium aa60 with asterisk for a small office.
The configuration:
AA60 is internal (IP 10.0.5.250)
TMG has 3 NICS: internal (10.0.5.2), external (10.0.3.2), DMZ (10.0.6.1)
NAT relationship between internal & external, Route rel. between DMZ and external.
CISCO PIX 501 as the edge (10.0.3.1)
i setted up rules on CISCO and TMG as follows
Internet--->CISCO (PAT 5060 to TMG-10.0.3.2 AND fixup protocol SIP and RTP)--->TMG (server publishing rule 5060 with "requests appear to come from the original client" AND for RTP from external to internal (publishing) and vice-versa (access rule)) ---> DIGIUM AA60
SIP Filter is enabled on SIP protocol.
Set up the VoIP Rules with the Wizard, but have a user-defined protocol
THE SITUATION:
unable to call from internal
When i call from external the extension rings, but when i answer i can't hear. The other side continue to hear ringing until it gives up.
Looking at the TMG logs i noticed that AA60 tries to initiate RTP connections to the internal interface of TMG (10.0.5.2) instead of to the Internet IP address of the provider.
Why, if i configured the SIP rule with "requests appears to come from the original client"??
Thanks in advance 4 any help.
