hi all,

i recently subscribe for an isdn and terminate it on a 3825 router.

i used it as a sip trunk for my asterisk. i'm a newbie when it comes to 
ISDN. and i've been experiencing some issues:

1. Call Hangup:

When hangup is initiated from the outside the extension (softphone/ip 
phone) does not hangup, is this normal? shouldn't asterisk hangup the 
extension as well when it receives the hangup properly from ISDN? or 
maybe it's because asterisk does not detect the proper hangup?

2. Caller-ID for incoming calls:

When i call in to the ISDN using my hand phone there are times that my 
handphone number shows up on the extension but there are times it does 
not, what it shows is the main isdn number i subscribed to. please sniff 
below:

Correct Caller-ID:

U 202.202.202.203:59049 -> 202.202.202.202:5060

   INVITE sip:[email protected]:5060 SIP/2.0..Via: SIP/2.0/UDP 
202.202.202.203:5060;branch=z9hG4bK53D21C6..Remote-Party-ID: 
<sip:[email protected]>;party=calling;scre
   en=yes;privacy=off..From: 
<sip:[email protected]>;tag=AD146FC4-F34..To: 
<sip:[email protected]>..#

i called using my mobile (33232333) to 82301000 on the extension i see 
the correct caller-id 33232333.


Wrong Caller-ID:

U 202.202.202.203:59123 -> 202.202.202.202:5060
   INVITE sip:[email protected]:5060 SIP/2.0..Via: SIP/2.0/UDP 
202.202.202.203:5060;branch=z9hG4bK53D51EE1..Remote-Party-ID: 
<sip:[email protected]>;party=calling;scr
   een=yes;privacy=off..From: 
<sip:[email protected]>;tag=AD14FB28-1D36..To: 
<sip:[email protected]>..

i called using my mobile (33232333) to 82301000 on the extension i see 
the correct caller-id 82301510 which is wrong (this number is the main 
line for my isdn)


Can anyone please advice ow do i start troubleshooting this issues?
TIA.

Regards
Ron
