Hi, Support,
when we tried to compile the old softphone against the upgraded sdk, we found out some api's signature definitions have been changed, such as the following compiling error we got:
SetAudioOutDataType' : function does not take 2 parameters
C:\Program Files\LanScape\VOIP Media Engine\5.11\Software Examples\SingleLine Phone\SingleLine PhoneDlg.cpp(1913) : error C2660: 'SetTxIvrDataType' : function does not take 2 parameters
and also some data structure definations have been changed, for example,
"AUDIO_BW_MULAW_8K = 0," was used in previous AUDIO_BANDWIDTH defination, but in the following new defination, it is actually the same thing, but with "AUDIO_BW_ULAW_8K = 0," which has different name, this caused all of the references to this data structure in our old versioned code have to be changed. So is there a quicker way fro your point of view that we can adopt to port our old versioned code on the new sdk?
thanks,
will
typedef enum
{
AUDIO_BW_ULAW_8K = 0,
AUDIO_BW_ALAW_8K,
AUDIO_BW_G729,
AUDIO_BW_G729A,
AUDIO_BW_ILBC_20MS,
AUDIO_BW_ILBC_30MS,
AUDIO_BW_PCM_8K,
AUDIO_BW_PCM_11K,
AUDIO_BW_PCM_22K,
AUDIO_BW_UNDEFINED
}AUDIO_BANDWIDTH;

Hi, Support,
I disabled all of the previous api calls which have conflicts with the upgraded sdk, and made the compilation go through, then when we start the softphone, it stays at "System initializing...pls wait" status and could not start the engine, after we click to close the softphone, it also shows the following error message:
"Error: The following telephoney error was detected:SipBandwidth error:Error 13"
We guess upgrading is mainly done in the LMEVoip.dll, and some new features and modifications are put in the SipTelephonyApi.h and we also browsed the registry, we noticed a new key has been added in addition to that for version 5.10, so actually the softphone should just go to InstallDir key in te registration to follow the value:C:\Program Files\LanScape\VOIP Media Engine\5.11\ to find the right Dll to start the engine, if we undersdand correctly.
your help are very appreciated.
regards,
will

Will,
Sorry for the delay. Our office was closed yesterday for holiday.
1)
Yes there have been some minor changes to the API that will cause some source code changes. Please read the "VOIP Media Engine Version History.pdf" file that is part of your install image. The changes that need to be made to application source code are simple and will not take a long time. There have been changes made to 2 enumerations and simplifications made to 3 IVR procs and 2 audio out procs. To change these in your code will not take long. Just build your app and where the compiler generates errors, change the code. Also make sure your project is using the v5.11 SipTelephonyApi.h header file. The procs that have changed are:
OpenRxIvrChannel()
SetTxIvrDataType()
GetTxIvrSampleBlockSize()
SetAudioOutDataType()
GetAudioOutSampleBlockSize()
And th3 2 enumerations that changed are:
AUDIO_BANDWIDTH
MEDIA_FORMAT_AUDIO
2)
To make sure that you do not have conflict with an earlier installed version (i.e. 5.10), make sure the environment PATH of the host machine is set such that it references the v5.11 DLL Bin directory before the v5.10 Bin directory. Alternatively, you could just rename the v5.10 DLL to some other name so it will never be found while you do your 5.11 testing.
