[Spce-user] Response to 180 and 183 when 100rel required

[John Murray]

Hello,

 

How can I enable reliable responses to 1XX messages?

I have 2 PSTN suppliers 1 requires 100rel and the other supports it.

 

The SPCE is not responding to the 183 and the provider is timing out after 3
retries.

 

SIP/2.0 183 Session Progress

Require: 100rel

 

Best regards

 

John
