[SR-Users] How to get $fU and $tU from MSRP module?

[Henning Westerholt]

(please keep the list in CC)

Hello,

I see – its kind of pseudo-SIP message that is presented in the cfg in this route. And it seems that you want to access the cpim body.
You already checked that the $msrp(crhop), $msrp(nexthop) and $msrp(prevop) etc.. are not working for you?

It’s probably not the best way, but what about using $msrp(body) to get the body and then using a regular expression (like a transformation) on this to get the From/To?

Cheers,

Henning

Yes, I logged, but only got <null> for both $fU and $tU.

Hello,

I am not that familiar with the MSRP module, but have you tried to just log/access the $fU and $tU in the event_route[msrp:frame-in]?

Cheers,

Henning

Hello!
I want to get $fU and $tU from event_route[msrp:frame-in] in order to filter out MSRP messages sent by a specific sender and received by a specific receiver, I know I can get message content from $msrp(buf), the message content is like this:
MSRP 7a57f552155926c0 SEND
To-Path: msrp://172.18.0.14:6060/9d8da4a34dc2102959e7;tcp msrp://172.18.0.12:5060/msrp-6142fc2b-84-1;tcp msrp://172.18.0.2:34862/2a67b54ae0750b7d82aa;tcp

I want to get alice and bob from the content below：
From: sip:alice at ims.mnc001.mcc001.3gppnetwork.org
To: sip:bob at ims.mnc001.mcc001.3gppnetwork.org
DateTime: 2021-09-16T09:23:49.339805+00:00
someone can suggest some method. In other route like request_route we can use $fU and $tU to access them.
