[asterisk-users] Two B-Channel Transfer (2BCT/TBCT) Trobule on DMS100 PRI

[Jacob Lefkowitz]

I have not been able to get two B-channel transfer to work on DMS100 PRI.  I
consistently get the following errors:

[Nov  6 11:12:49] ERROR[2774]: chan_zap.c:8178 zt_pri_error: ROSE RETURN
ERROR:
[Nov  6 11:12:49] ERROR[2774]: chan_zap.c:8178 zt_pri_error:    OPERATION:
RLT_OPERATION_IND
[Nov  6 11:12:49] ERROR[2774]: chan_zap.c:8178 zt_pri_error:    ERROR: RLT
Not Allowed

I have tried on two different DMS500 switches with two different phone
companies.  The phone companies swear it is enabled on their end, and they
are billing accordingly :).  This is using Asterisk 1.4.13/Zaptel 1.4.5.1
(although it also did the same on earlier 1.4 versions).  Has anyone been
successful with this?
