We have such scheme of passing of a call.
CISCO - PRI E1 ROU=5 - the MX ONE TSW - PRI E1 ROU=5 - CISCO
The call comes to CISCO on H323, is transferred to processing for example through LCR and under certain circumstances has to return on CISCO and to leave her for example on SIP or H323 further.
CISCO in this case as a working example, in her quality can act any other station.
If in ROU=5 two and more streams of E1, then everything works normally and problems don't arise.
At one stream of E1 in ROU=5 return of a call comes to an end with failure.
In ALEX it is described that in the station there is a certain block of return which processes such situation and doesn't allow to make similar a call.
Trace of such call from number 6291 coming from CISCO on ROU=5 with set 736291 is given below. DEST=73 it is appointed on ROU=5 and has to return on CISCO.
But it doesn't occur.
Interests a possibility of positive processing by the station of this situation.
Audit of the TSWSP8 station.
