IMG 1010 - Pass through ‘+’ sign in the user part of URI

 

The IMG supports the passing of the  ‘+’ sign from the incoming SIP side to the outgoing SIP side, or the removal of the "+" if you do not want to pass it through. This process is only applied to INVITE.

Configuration:

This feature is enabled in the IMG 1010 - SIP Profile - 10.5.3 with the Append (+) for Headers and Remove (+) for Headers fields.

This feature can be applied to the following headers in the INVITE:

  • R_URI

  • FROM

  • TO

  • P_ASSERTED

  • P_PREFERRED

  • REMOTE_PARTY_ID
     

The Contact header is not put into the bit mask, but ‘+’ is supported in the Contact header if it is included in the incoming Contact.

The ‘+’ is not supported for routing or translation; only a simple pass through.
