to look at the new patch set (#3).
Change subject: Remove speech codec list from bearer_cap for phase 1 mobile station ......................................................................
Remove speech codec list from bearer_cap for phase 1 mobile station
According to TS 04.08 Clause 10.5.4.5.1, the octet 3a etc. shall not be included, if only GSM full/half rate speech version 1 is supported.
As phase 1 mobile stations only support FR and HR speech, the speech list in the bearer capability must be reduced to the codecs listed above. If there is none of these codecs left, the call is rejected.
The octet 3a etc. must be omitted when encoding bearer capability for phase 1 mobile stations. This is done by removing the speech list.
I do not use a "codec filter", because it is not required. The phase 1 mobile station can only respond with codecs it supports, so no filtering is required.
