Difference btn Restcomm CCA and GX resource adapters

Question

I want to use a service to receive GX interface messages (Credit Control Request) but I found that CCA and GX RAs both are serving CCR with code 272 in restcomm (Mobicents) implementation. I have below questions:

1. What is the difference between CCA resource adapter and GX resource adapter in restcomm jain-slee!?
2. So what is the right one that i should use?
3. Are implementations complied with 3GPP or IETF standards?

thanks.

Answer 1

GX Restcomm implementation is based on 3GPP TS 29.210 V6.7.0 (2006-12) and it depends on Diameter Credit-Control Application RFC . However, the differences between CCA and GX Resource adapters:

1. CCA is configured to accept messages with:

   [Vendor-Id:0; Auth-Application-Id:4; Acct-Application-Id:0] and [Vendor-Id:10415; Auth-Application-Id:4; Acct-Application-Id:0] BUT Gx accept messages with: [Vendor-Id:0; Auth-Application-Id:16777224; Acct-Application-Id:0], [Vendor-Id:10415; Auth-Application-Id:16777224; Acct-Application-Id:0] , [Vendor-Id:0; Auth-Application-Id:16777238; Acct-Application-Id:0] and [Vendor-Id:10415; Auth-Application-Id:16777238; Acct-Application-Id:0]

2. GX has more AVPs to be received.
