Migrating to 1.15.0

1.15.0 numbers the Node-Functionality AVP (code 862) as TS 32.299 §7.2.113 does. Values 0 to 7 (S-CSCF to IBCF) are unchanged. Above that siphon had its own table, so records from an E-CSCF, an ATCF or a node configured as mmtel went out as another node. No siphon.yaml key stops working.

name	sent before	sent now
ecscf	9 (P-GW)	11
atcf	10 (HSGW)	15
mmtel	11 (E-CSCF)	6 (AS)
scscf-restore, tpf, atgw	8, 12, 13	not a value
sgw, pgw, hsgw, mme, trf, tf, proxy, epdg, tdf, twag, scef, iwk-scef	not accepted	8 to 21

siphon.yaml

rf.node_functionality and ro.node_functionality set to scscf-restore, tpf or atgw still load. siphon logs that the name is not recognised and leaves the AVP out of the records, as it always did for an unknown name. Pick the function the node has from the table, as for an application server.

Python scripting API

node_functionality="scscf-restore", "tpf" and "atgw" on diameter.ro_ccr_*, diameter.rf_acr_* and diameter.ro_session raise ValueError. "mmtel" is still accepted and sends 6.

Rust library

NodeFunctionality::SCscfRestore, Mmtel, Tpf and Atgw are removed. Ecscf is 11 and Atcf 15. SGw, PGw, Hsgw, Mme, Trf, Tf, ProxyFunction, Epdg, Tdf, Twag, Scef and IwkScef are new.
