SIP error SIP/2.0 400 Invalid Contact URI Scheme

[crashtest1000]

We are getting the following error when we make a SIP call,

SIP error SIP/2.0 400 Invalid Contact URI Scheme

The carrier is saying it is because we are putting the + in front of the number in the of the SIP Display name Alias on the user.

The System apears to be adding the plus automaticlly does anyone know how to stop it adding the + we dont want to change to a URI name.

Its an IP500 V2 running 6.0

Did you perhaps used the + on the prefix at the sip trunk ?

honey, i fried the IP Office !!!

Sarcasm, it's only one of the services I offer.

If only, the system appears to be putting it in.

No other carriers have an issue with this but this one we are dealing with will not accept calls with the +

Untick "Use tel uri" on the sip line.

Hi Bas1234

Yes we have already unchecked this option not sure what will happen if it is checked

 

[Bas1234]

Then try to turn it on, I missed the RX part in the trace. RX is what they send, and that's a Tel URI and not a Sip URI.
