This won't work .
*21* from md excepts a acknowledge from the other side .
The service request is rejected by the other side.Hence "service not accepted" .
To setup qsig with network services to other brands pbx/other than a md you must use ISO-QSIG .
The network (other side) must support/be setup as
standardized ISDN ISO QSIG Generic Functional protocol
and the standard supplementary services Call forwarding(*21), Call transfer and additional network feature Path replacement will be supported if implemented on each side.

1.4 Interworking with non-ASB 501 04, supporting standard ISDN services
Basic Call, Calling/Connected Line Identification, Advice Of Charge and Name Identification are supported according to ECMA-QSIG and ISO-QSIG standards, and can thus be supported when interworking with a non ASB 501 04 which supports the same service.
Call completion is supported according to ISO-QSIG and can be supported when interworking with a non ASB 501 04 which supports the same service. In that case the option Type of protocol to use for Supplementary service Call back/Call completion in the ADC parameter must be set to Standardized Generic Functional Protocol.
Call forwarding is supported according to ISO-QSIG and can be supported when interworking with a non ASB 501 04 which supports the same service. In that case the AS parameter, PARNUM=223 Type of network services must be set to Call forwarding and the entire network segment must use the same type of service. The ASB 501 04 exchange has to be R8 or higher.
Call transfer is supported according to ISO-QSIG and can be supported when interworking with a non ASB 501 04 which supports the same service. In that case the AS parameter, PARNUM=223 Type of network services must be set to Call transfer and the entire network segment must use the same type of service. The ASB 501 04 exchange has to be R8 or higher.
Path replacement is supported according to ISO-QSIG and can be supported when interworking with a non ASB 501 04 which supports the same service. In that case the AS parameter, PARNUM=223 Type of network services must be set to Path replacement and the entire network segment must use the same type of service. The ASB 501 04 exchange has to be R8 or higher.
Other standard services can be supported in transit situations. This requires that the involved ISDN routes are initiated for support of the Generic Functional protocol, i.e. the VARI parameter in the RODAI command must be set accordingly.
