Hello,

I am running freeswitch 1.10.3.  I have several DID's on this system.  Some work without any issues, but some somehow get some wierd characters added to the SIP message.  I have already verified that there are no extra characters on the number.  It appears to be a certain combination that it is happening to.  If I change the last number from 1024 to 1023, nothing get added but on 1024 it does.  Any suggestions on why this is happening and/or how to fix/patch this?

Looks like a zero width char got in somewhere

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?

Have you a trace from the leg from the poly?

It could be a memcpy copying too much. Open a github issue with logs  and pcaps.

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,

I am doing a pcap on the inbound and outbound leg.  The pcaps shows that the characters are not being added until it sends the invite out it's Gateway.  Before then the pcap does not show any anomalies.  Somehow on the invite to the carrier the characters are being added not before.  I again have made sure this is the case.  I wrote a Lua script that would strip out any characters before, after and in between the called number.  And this script is run right before sending the call out.  I know how to control the call prior to it hitting the GW, what I don't know how to do is modify the invite this far along in the call.

It seems my helpful post was delayed by a day…so ignore it now.  For some reason my posts are very slow to reach the list.

turn on sofia debug and sofia global siptrace, and get a pcap and open a bug including the above data so someone can evaluate it
