CUBE supports interworking of dynamic payloads. But it appears that the scope of the supported interworking functionality is limited to nte and nse (telephony-events and sse), and not to other parameters. But what if one call leg has the following (default/standard) values of 96, 97, and 98 in SDP Offer:
…
Rtpmap:18 G729/8000
Rtpmap:0 PCMU/8000
Rtpmap:96 telephone-event/8000
Rtpmap:97 v150fw/8000
Cpar:a=sprtmap:98 v150mr/8000
….
Fmtp:96 0-16,32-35
Fmtp:97 1,3
…
Cpar:a=sprtmap:98 v150mr/8000
And the other call leg responds in SDP Answer with non-standard X, Y, and Z (e.g. 112, 118, and 121 instead of 96, 97, and 98). Based on what I’ve seen online, CUBE supports interworking of nte and nse, but not other values (so, we could remap 96 but not 97 or 98). Is that correct? Or is there a way to interwork two calls legs that use different values for v150fw and sprtmap?
