Hi all,<br>
<br>
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.<br>
<br>
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).<br>
<br>
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.<br>
<br>
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.<br>
<br>
Please help to configure FS to send option something like this-<br>
<br>
<br>
<span style="font-weight:bold"><b>OPTIONS sip:10.129.43.154:5060;ttl=0 SIP/2.0</b></span>

i.e. They want OPTION with only IP address not user@IP. So that on recieving any call they can transfer it to our FS.<br><br>Please Help. <br>Thanks<br>
