Summary:                    [patch] PCMA/16000 and PCMU/16000 support (hd
telephony)
Description: 
With this patch PCMA/16000 and PCMU/16000 will be accepted during the SDP
negotiation. Prior asterisk ignored the sample rate in the rtpmap lines of
the SDP body and changed the 16000 to 8000.. and so the negotiation between
the UAs failed.
Now the sample rate is parsed too, and for now PCMA/16000 and PCMU/16000
are supported by the new option flag AST_OPT_16000.

If the end devices can handle these codecs, Asterisk does not have to fully
support these codecs internally, as the RTP session is set up between the
endpoints. 
My patch is no internal support, but makes a successful sdp negotiation
possible between two devices, if both are able to speak PCMA/16000 or
PCMU/16000.
