Just google base64... It's a way on encoding binary data using only printable ASCII characters. There are other ways to encode data too.<div><br></div><div>If you're actually wanting to send the raw data though I've just read up the sofia api...</div>
<div><br></div><div>Create a sip_payload_t initialised by SIPTAG_PAYLOAD_INIT2(data,length) and then use it with the SIPTAG_PAYLOAD() macro.</div><div><br></div><div>That'll handle \0 bytes<span></span> correctly. Passing the data to SIPTAG_PAYLOAD_STR() won't as it'll treat it as a null terminated string.</div>

<div><font face="Verdana">Does it have to be sent as binary? How about
using something like base64 to encode it first?
<div><br></div>
<div>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.<br>
