[Freeswitch-users] To and From fields in SIP OPTIONS

[Victor Chukalovskiy]

Hello,

I should add that FS OPTIONS indeed cause trouble to some far-end 
implementations.
Not just because they only contain domains as indicated by Stanislav. 
But also because it's always the same domain both in From: and To: 
headers. Example:

From: <sip:*5.6.7.8*>;tag=ZZZ1Na2KacXcm
To: <sip:*5.6.7.8*>"

While this is probably standard-complaint, some implementations expect 
From: header to contain FS own IP. Example:

From: <sip:*1.2.3.4*>;tag=ZZZ1Na2KacXcm
To: <sip:*5.6.7.8*>"

Moreover, SIP gateway param "from-domain" has no effects on OPTIONS 
request From: header.... this param seem to be only parsed for INVITE & 
REGISTER requests.

Presently I don't have time for JIRA / feature request, so putting it 
here in case someone struggles with the same.
Maybe someone will be able to go ahead and improve this.

Cheers,
-Victor
