[OpenSIPS-Users] CallID shorting

Dear Team

 

We have a setup with multiple SBCs in line like

 

Access SBC -> Routing SBC -> Core SBC -> Interconnect SBC

 

On each level we apply topology hiding so the callid keeps increasing in length ending up with 200+ characters which is not manageable by all upstreams carriers. Some of those asking for max 40 char length callid.

 

Is there a way to keep topology hiding to all SBCs and decrease / minimize / control the callid length?

 

Best regards
