Re: [Sofia-sip-devel] Duplicated VIA headers of SIP REQUEST

[Michael J. <mi...@je...>]

If you add ;maddr=3D1.2.3.4 where 1.2.3.4 is the interface ip to bind =
to,
to the end of the url that you pass to the NUTAG_URL on nua_create then
it binds to the address specified in maddr but properly uses the first
part of that url for the via and contact.

Subject: [Sofia-sip-devel] Duplicated VIA headers of SIP REQUEST

Dear all,

=20

Did anyone know how to modify the Via header of outgoing SIP REQUEST by
using nua level apis? Because I want to fill the external IP of NAT that
I obtained (by using some else mechanism outside of sofia-sip).

=20

I add "SIPTAG_VIA_STR("SIP/2.0/UDP external_ip")" when creating the
handle that is used to sent out SIP REQUEST. But it cause the duplicated
Via header of REQUEST i sent, as following :

=20

Via: SIP/2.0/UDP 192.168.1.100;rport;branch=3Dz9hG4b......

Via: SIP/2.0/UDP external_ip

(It is not exactly I need)

=20

By using nua level api, is that any possible way to replace or remove
the original Via header generated by sofia-sip stack ?

Thanks for your reading, and looking forward to any possible solution?
