Hello All
 
  Could anyone explain please, if it's possible to place a call from TCL-application which would be considered redirected? I mean, I'd like to know how could I fill in "Redirecting number" field in ISDN Setup message. The standard "leg setup" operator places a regular call and only "calling" and "called" parties fields are used. The main goal is to inform external provider that the call was not initiated by the gateway, but just redirected by it. In this case it will be possible to pass calls through the provider even if "calling" number is not within the msisdn-range that provider gave us. In this case provider will check "redirecting" party for the allowed number. Afterall we expect to deliver proped Caller-ID to the called subscriber. For now, we have to supress real caller ID with the fixed number from our range. 
  Thanks in advance for any help.

Thanks for your reply!

I did try to set redirectNum parameter, but with no success: router takes it but there is still no redirecting party field in ISDN message.

Here is the leg setup call:

set callInfo(originationNum) 8612170985
set callInfo(redirectNum) 8612170994
set dest "79184442244"
leg setup $dest callInfo leg_incoming

and ISDN Setup:

Apr 12 20:45:08.540: ISDN Se7/1:15 Q931: TX -> SETUP pd = 8 callref = 0x0080
Sending Complete
Bearer Capability i = 0x9090A3
Standard = CCITT
Transfer Capability = 3.1kHz Audio
Transfer Mode = Circuit
Transfer Rate = 64 kbit/s
Channel ID i = 0xA9839F
Exclusive, Channel 31
Progress Ind i = 0x8283 - Origination address is non-ISDN
Calling Party Number i = 0x2183, '8612170985'
Plan:ISDN, Type:National
Called Party Number i = 0xA1, '79184442244'
Plan:ISDN, Type:National

Thanks in advance for your help!

Thank you very much for your reply, that helped!

My last question in this matter is about Original Called Number IE and Redirection Information IE. These IEs are required when passing call to the SS7 channel (considering that call goes to the signalling converter). I did found appropriate callInfo fields, however I can't find anything redarding how to set up the IEs on the ISDN interface.
Could you please explain, if my need is feasible?

Thank you in advance

Hi Raghavendra

Thank you for the answer
It still looks like all the IEs, that we are discussing are not passed "as is". At least, I don't see them from the ISDN trace taken on the remote side (telco switch that as5400xm is connected to). However I found that if I put "isdn supp-service calldiversion" on the Serial interface, then router will not provide "Redirecting number" in the ISDN:Setup but will put "Facility" IE. This IE contains some coded information which is passed to the remote telco switch which can't decode it. Do you think "Original called number" and "Redirection information" might be contained in that data?
