>From GSM 03.40 version 6.0.0:
Reply path procedure: A mechanism which allows an SME to
request that an SC should be permitted to handle a reply
sent in response to a message previously sent from that SME
to another SME. This may happen even though the SC may
be unknown to the SME which received the initial message.

In my understanding the reply path means whether the mobile
station (MS) should use the originator's SMSC when 
replying to the message, or not. 

In our case the reply path is automatically set to 0 in MOMT
case, regardless the original value set by SME,
because the subscribers are usually allowed to submit
towards their own SMSC only. If user A sends a message to 
user B (assuming that they have different operators), and
the reply path is enabled, when user B replies, the MS 
tries to use A's SMSC, but he will get refused by the SMSC.

In AOMT case globally it can be changed, but it is
restricted in the profile.

The point is that the reply path indicator shows if the SC
should handle the 
reply, and not if the user should reply. 

Thanks for the comments,
Peter
