Hello
We are doing some testing with an access provider and cannot originate
calls from the access network. The access provider has an SBC that also
includes some routing functionality. This SBC connects to our bono node by
IP address. The SBC does not do DNS name resolution.
Our understanding is that the user agents are populating Route headers in
invites with the content of the Service-Route. The Service-Route is <
sip:sprout@domain:5054;transport=TCP;lr;orig>. The SBC is then trying to
route the invite to sprout which fails firstly because it cannot resolve
the name and even if it could would not be trusted by sprout.
Can the Service-Route header be removed from the 200(Register)? I would of
thought that with the horizontal scaling that Clearwater uses that there
would be no need to use this header.
If the Service-Route header is required then can it also include the bono
node first? For example:
Service-Route: <sip:<bono pulic ip>;lr>,
<sip:sprout@domain:5054;lr>
Regards
Glenn Walbran
