I tried to setup Cisco 3825 as SIP-toSIP GW between customer's Voice Gateway (Quintum AXF, 80.251.131.27) and "RTU" Soft-Switch (cluster's IPs: 80.251.131.132 and 80.251.131.133 and internal ones 10.0.99.121, 10.0.99.221 and 10.0.99.99 - shared Heartbeat IP).
When I connect Quintum directly to RTU (making corresponding settings on RTU and Quintum) - all works fine! The matter is not in Quintum or in RTU. This is verfied.
Cisco3825 (80.251.131.28) accepts SIP INVITEs and sends ones on the same interface (one interface configuration what is "highly recommended"). But it doesn't help. Call looks like in the following trace got on RTU (10.0.99.111 is my phone for simplification):
17:44:50.930821 10.0.99.111 -> 10.0.99.99 SIP/SDP Request: INVITE sip:4996540908@10.0.99.99;user=phone, with session description

17:44:51.598557 10.0.99.99 -> 10.0.99.111 SIP Status: 503 Service Unavailable
17:44:51.599091 10.0.99.111 -> 10.0.99.99 SIP Request: ACK sip:4996540908@10.0.99.99;user=phone
This trace has been got from RTU side. At the moment when 183 Session Progress is coming on the phone connected to Quintum's analogue port one ring is heard (single). When 503 Service Unavailable is coming I get short rings on my phone, Quintum's Phone become silent, because Quintum judging on its traces gets CANCEL from Cisco.
I have tried a handful of IOSes, with "T" of without it, but effect is always much the same.
How-to? Help, please!... :-)
