[Freeswitch-users] How to encapsulate binary code to SIP body

[windy]

Hi, Steve

The data is not very large. Normall it's an ISUP message and no more than 256 bytes.

For the base64 encode, can you give an example?


Thanks

Does it have to be sent as binary? How about using something like base64 to encode it first?


You also want to be careful sending a large amount of data in this way. If your packet gets larger than the PMTU then you'll get packet fragmentation which SIP/UDP doesn't handle well.

Dear support

I now need to encapsulate one binary array to FS SIP body. To be specific:
(1) I encoded some info when getting incoming 183. 
(2) The encoded info need to be encapsulated as one of content in SIP body like
      content-type=application/test
      content-length=74
      --boundarycode
      1233444444444 --------------------binary code

I'd like to add to the sipbody by using:
     nua_Respond(...
                        ...
                      SIPTAG_PAYLOAD_STR(), RAG_END).

Well, As you know, SIPTAG_PAYLOAD_STR is for string, it will truncate the binary array before it encapsulats the binary code to SIP body.


Is there any way to encapsulated my binary array to the SIP boday with "nua_Respond"?


Thanks
Windy
