Unrecognized garbage 'Reserved' in WCTDM/4/2

Here's a call coming in over PSTN to dahdi/4, connected to a local extension dahdi/1:

   -- Executing [s@incoming-pstn-line:1] Answer("DAHDI/4-1", "") in new stack
..........
   -- Executing [s@incoming-pstn-line:6] Dial("DAHDI/4-1", "DAHDI/g0,36") in new stack
   -- Called g0
   -- DAHDI/1-1 is ringing
   -- DAHDI/1-1 is ringing
   -- DAHDI/1-1 answered DAHDI/4-1
   -- Native bridging DAHDI/4-1 and DAHDI/1-1
   -- Hanging up on 'DAHDI/1-1'
   -- Hungup 'DAHDI/1-1'
 == Spawn extension (incoming-pstn-line, s, 6) exited non-zero on 'DAHDI/4-1'
   -- Hanging up on 'DAHDI/4-1'
   -- Hungup 'DAHDI/4-1'

I'm on dadhi/1. After 10-15 minutes, the call just drops.

****** ADDITIONAL INFORMATION ******

   -- Executing [s@DialOut:16] Dial("DAHDI/1-1", "DAHDI/4/xxxxxxxxxx") in new stack

I'm trying dahdi svn to see if that helps. Can't build dahdi-linux because of pciradio, but I did build dahdi-tools from svn.

./xpp/dahdi_hardware -v
pci:0000:01:05.0     wctdm+       e159:0001 Wildcard TDM400P REV I

so the "garbage" reference no longer appears.

After the asterisk-dev [1] discussion, is this still an issue?  I'm a little uncertain from the comments.

I've installed dahdi from trunk. So far no dropped calls. But I haven't really used it much either. It's probably a good idea to close this. I'll open another if the problem returns.

Thanks.

Sounds good.  Thanks.
