[Sip-implementors] FROM header in SIP INVITE shows:[e-mail]

[souvik pal]

Dear Team,

We have the following call case:

Call is originated from PSTN.

We have GMSC node ( transit switch) which receives an INVITE containing
encapsulated ISUP IAM message in SIP-I interface.

The GMSC further sends INVITE in SIP interface to the end node (MSS) in
which the FROM header does not contain the calling party number.

The FROM header is displayed as :
From: <sip:unavailable at unknown.invalid>;tag=2609184897

The incoming INVITE towards GMSC contains FROM header containing calling
party number and is displayed as:

From: <sip:4959516681 at 10.242.30.10;user=phone>;tag=p9343wwl-CC-23.

The incoming ISUP IAM message has the following parameters present:

CgPN ( calling party number):4959516681

NOA (nature od Address)=National

Presentation restricted ind= *Presentation allowed*

CallingPN incomplete ind = Complete

Screening ind = Network provided

Numbering plan ind = ISDN (Telephony)

Pls help us investigate the reason why FROM header for INVITE sent from
GMSC does not contain calling party number and is displayed as
unavailable at unknown.invalid.


Thanks in Advance!

Based upon what you provided, I'm not sure why the GMSC behaved as you
indicated. You should be able to obtain the answer from the GMSC
administrator or vendor. For instance, there might be service or trust
reason to perform the mentioned conversion.
