I want for any reason of hangup asterisk will return 503

41 503 NORMAL_TEMPORARY_FAILURE temporary failure [Q.850]

This cause indicates that the network is not functioning correctly and that the condition is not likely to last a long period of time; e.g. the user may wish to try another call attempt almost immediately.

Although the ISDN interworking isn’t really there for your intended purposes, but rather to give a reasonable approximation of the ISDN clearing cause, have you tried the other codes in https://tools.ietf.org/html/rfc3398 that translate to 503.

Failing that look for the switch that does the translation, in the source code. In earlier versions, it is in hanugp_cause2sip() in chan_sip.c, but that file has been restructure and split, since.
