We are having a very strange problem. We cannot hold more than 5 minutes or so 
on a few different calling methods on SipX. We are running the latest version 
from ISO.

We have tested the following configuration.


Inbound Call (E1) --> Cisco AS5350 --> SipX --Local Extension ---Fails After 5 
minutes or so (The Cisco and SipX box are on the same network and connected 
through a switch)

Sip Provider  A --> SipX --> Local Extension -- Fails after 5 minutes or so
Local Extension --> SipX --> Sip Provider A -- Fails after 5 minutes or so

Sip Provider  B --> SipX --> Local Extension -- Fails after 5 minutes or so
Local Extension --> SipX --> Sip Provider B -- Fails after 5 minutes or so

Sip Provider  C --> SipX --> Local Extension -- Fails after 5 minutes or so
Local Extension --> SipX --> Sip Provider C -- Fails after 5 minutes or so

Local Extension --> SipX --> Local Extension (NAT) -- Doesnt Fail (Extensions 
are connecting over the internet and arent on the same subnet)
Local Extension --> SipX --> Local Extension (No NAT) -- Doesnt Fail 
(Extensions are connecting  over the same subnet/network)

So obviously this is a SipX internal issue and not related to a specific sip 
provider or gateway.....

Any help fellas?
