[OpenSIPS-Users] 100rel / PRACK Interworking

[Antonios Psaras]

Hello Johan.

 

I am sure b2bua can handle it but it will require lots of resources and heavy redesign in our case.

 

Thank you for your response though. 

 

Regards

 

Antonis

I think you could handle it in b2bua mode but in my implementations, I always handle that on the edge sbc (same thing for update).

Hello Antonio,

 

PRACK is actually an endpoint feature, at the proxy level you can only fake it...

Dear Team

 

As many carriers requires 100rel for interoperability reason with IMS, the need for 100rel interworking is mandatory. Is there any solution available to implement that on OpenSIPs Proxy level?
