[Freeswitch-users] Gateway Configuration with No Authentication

[Vishal Kakkar]

Hi all,

We are trying to use FS to handle incoming call from SIP provider. Provider
doesnt have any authentication because its all inbound traffic. They have
configured their SIP trunk to point to our FreeSwitch Box.

We have also configured one gateway in eternal/provider.xml with the IP of
provider and disable the registration as provider is not expecting the
same(they dont have any user configured for us, as they are using their box
in trunk mode).

Issue is that when an incoming call reaches to provider, we are not getting
any INVITE from them and its being dropped at the IP that we have added as
gateway. Reason shared is that they are expecting us to have heartbeat with
their IP.

When we turn ping option, it sends OPTION message but username is getting
appended to TO and FROM uri's so that cause 404 No User found response.

Please help to configure FS to send option something like this-


*OPTIONS sip:10.129.43.154:5060;ttl=0 SIP/2.0*

                       Via: SIP/2.0/UDP 10.129.43.23:5060;
rport;branch=z9hG4bK-

                       6df4-1156281802-19999-423

                       Call-ID:
5aa9-1e61-7222006212322-chiloe-0 at 10.129.43.23

                        CSeq: 1 OPTIONS

                       Max-Forwards: 70

                       *To: <sip:10.129.43.154;ttl=0>*

                       *From: <sip:10.129.43.23>*
;tag=95ffcd055e0f78f7d5d397020e8

                       9288db5f2

                       User-Agent: Dialogic-SIP/10.3.2.57 chiloe 0

                       Contact: <sip:10.129.43.23:5060>

                       Accept: application/ sdp

                       Content-Length: 0

i.e. They want OPTION with only IP address not user at IP. So that on
recieving any call they can transfer it to our FS.

Please Help.
Thanks
