Sip Header - failing over the route


Recommended Posts

i am having an issue that when we send an outbound call it sends along the User Info/Ext name

and we do termination with level 3 and they will reject the traffic since it doesn't not mach with there cname


Is that a problem with the Polycom phone or the service provider? The PBX is a B2BUA, so it does not really matter what the Polycom sends when the INVITE goes out to the service provider. I know we have some customers using Level 3; there must be a way to set up the trunk so they eat it.
