Hello all, 

We are testing Asterisk 1.8.8.1. In the following scenario, peer 54321 dials 
12345:

INVITE sip:12345@10.1.1.88 SIP/2.0
Record-Route: <sip:10.1.1.86;lr=on;ftag=5ebe58983f6c0c84o3>

To: <sip:12345@10.1.1.86>
Call-ID: adc7c928-b6f6d534@10.1.1.86
CSeq: 102 INVITE
Max-Forwards: 69

Peer 54321's caller ID will be blocked, since it enters the following context:

[outgoing]
exten => _X.,1,Log(NOTICE, Test)
exten => _X.,n,Set(CALLERID(num-pres)=prohib_passed_screen)
exten => _X.,n,Set(CALLERID(name-pres)=prohib_passed_screen)
exten => _X.,n,Dial(SIP/${EXTEN}@Peer)
exten => _X.,n,Hangup()

When asterisk dials peer 12345, it rewrites the "From" header  ("asterisk" 
<sip:asterisk@10.1.1.88>) instead of keeping it intact. The "Remote-Party-ID" 
on the other hand, is correct.

Please note that in sip.conf  we have set:

trustrpid = yes    
sendrpid = yes

Any input will be appreciated!
