[Freeswitch-users] weird extra characters

[TTT]

If you do a packet capture, are these characters really coming from the Polycom, or is freeswitch adding them on the incoming session?  (Showing in the SDP)

 

I missed first part of discussion – but interested

Hello,

 

This is a Debian 10 box running FusionPBX.  There is no windows on this.  Polycom phone makes a call and these characters are being added.  It only add the characters to a certain combination of numbers.  If I change the callerID to be 1023 instead of 1024 it works.  Also the polycom does not have the caller id set on the registration.  So something is adding it to the outbound leg.  I am just trying to get more info on how fix it.  Just googling " U+202C POP DIRECTIONAL FORMATTING" does not help much.  it is adding it on the sip invite not before, so my application does not have any characters.  I have made sure to strip anything before sending it to the Gateway.  Could someone please point me in the right direction?
