A quick introduction to what I'm trying to do: I have two SIP profiles, "internal" (port 5060) and "offpremise" (port 5070). Both of these profiles are recording registrations to the same registration db, so they can be reached by user/nnn. When a device leaves the local LAN and heads out into the field, firewall port translation maps port 5060 to 5070, so FS "knows" the extension is now off-premise. All profiles on the box are set to inbound-late-negotiation and inherit-codec, to reduce transcoding. What I would like to do is set a very restrictive list of codecs on the "offpremise" profile, so that an exension registered to "offpremise" only sees a set of low-bandwidth codecs. To facilitate this, I have set outbound-codec-prefs on the profile. After much testing, I have determined that "outbound-codec-prefs" in this configuration ends up ADDING codecs to the offer, and will not remove any codecs offered by the A-leg. Interestingly, inbound-codec-prefs seems to remove codec from the A-leg offer. So, my question: is there any way of restricting the list of codecs offered on the B-leg using the profile configuration (and not from within the dialplan)? If there is any answer at all, I'd suspect it's one of the following: * a global setting that changes the behavior of outbound-codec-prefs to be restrictive, instead of additive (the source doesn't seem to suggest this) * a way to set absolute_codec_string (or other variables) from within the profile itself * a way to set a variable (again, likely absolute_code_string) to the registration instance so the codec list can be explicitly specified * any other far-out ideas for accomplishing this kind of seamless "roaming" Any ideas or hints greatly appreciated.
