^4 [Asterisk-Users] problem with chan_unicall.c for MFC/R2 with asterisk

[HO SIN]

Dear Steve,  I thank you for your extensive support on R2 so far.
 
I am implementing it for Brazil, while I remotely do so.  It seems from the list, Daniel Bichara on Fri Oct 1 09:30:29 CDT 2004 and recent Leonardo Gomes Figueira on Fri, 19 Nov 2004 12:28:18 -0200 seem to have succeeded in implementation itself, though having another trouble each.  Also I noted your comments about Brazil's auto collect-call.

 
Here is a verbose log of asterisk when startup, among which I extracted part of unicall-related:

I set in zaptel.conf an idle pattern as "1011" while Brazilian R2 ignores CD bits.  ZTTOOL works fine and can monitor the status of signalling, and when inseizing it displays these AB=00 but on Asterisk the following displays:

Any suggestions ??

OK, fixed that one.

I am in the process of updating to the latest asterisk, but right now 
chan_unicall will only work with versions of * a month or more old.

Which version of R2 are you using? Most use the ABCD bits in the same 
way. China and Thailand are different. The code should be allowing for 
those. It certainly works OK for China.
