Hello there,
I need to strip away the first digit "0" from the username of the Header
>From on an incoming INVITE message.I had already used the uac_replace_from when adding
digits to the from field on outgoing INVITE but stripping a digit seems harder for me.
Can somebody help me?
Thx

you can use the substr transformation to get read of leading
0 in an
avp/var, and then use the result in uac_replace_from.

Hi,
can I ask a question in regard to this thread. Is it valid according to
standards to alter the From-header in a SIP INVITE?

not recommended as some UAs use it to identify the dialog, but some time
you are forced by the business you offer, In that case you should take
care to restore it in the messages going opposite direction.

Is it not a typical way to define callerid num in calls to PSTN gateway?
AFAIK is better using RPID header but...

SIP version 1 (2543) used From header to identify the dialog so it's not
recommended to change the From header to be backwards compatible (is there
any RFC 2543 SIP endpoint around??...).
SIP Version 2 (RFC 3261) uses tags to identify dialogs so you should be able
to change the FRom header except the tag.
Recently there was an
RFC 4916 that specifies how to identify the connected identity and how
to make a change in the From but I think this is far beyond what you
are trying to achieve.
There are additional headers (Remote_PartyID, and related) that can be used
to specify an identify of the calling party..
nice theory,
Sam.

Sure is RFC 4916 ?
It doesn't exist :(

New subject: R: [OpenSER-Users] Manipulation of the From header username
I appreciate all the discussion about this thread but there is someone that can help me
how to strip the first digit "0" from the username from header (I have learnt
that is safe to make it).
Thx again

Hi Michele,
you should be able to do this with the "Textops"-module in OpenSER:
http://www.openser.org/docs/modules/1.2.x/textops.html
Take a closer look at the "subst"-function, there's an example with the
"To"-header.
