[Freeswitch-users] FreeTDM hangs on Partial PRI

[Phone]

We are using

FreeSWITCH Version 1.0.head (git-8825b6e 2010-11-28 17-15-39 -0500)

WANPIPE Release: 3.5.14

Hardware is Sangoma A101

Partial PRI D-chan=24 B-chans=16-23

We are having trouble with the Partial PRI (channel 16) getting stuck in 
a state where it cannot take calls.  This happens intermittently.  The 
system may run several days or even a week or two without having the 
problem.  It seems that the channel is getting stuck in some odd state 
when trying to hang up.

To resolve this, we unload the FreeTDM mod, restarting Wanrouter, and 
then reload the FreeTDM mod.  This clears the channels and allows the 
system to take calls normally again.

In testing we have also observed the following conditions:

1. Place a call in.  Cannot complete. Hang up.
2. Place a call in.  It completes and works correctly.
3. Place a call in.  Cannot complete.  Hang up.
4. Place a call in.  It completes and works correctly.

The above pattern can be repeated multiple times, with the same result.

Here is some log info:

Hope this information is useful.

Thanks.
