one further note on the missing md5 file:

As it seems it is only used to generate a pseudo-random 32bit value for use in the SSRC: I'd rather not introduce a copy of MD5 for that.

There are two options to take:

1. simply use the same [not very random] method as we use for the TMSI

2. introduce a dependency to openssl and use that. Given that nanoBTS also support OML/RSL over SSL/TLS, I think sooner or later we will have to add that dependency anyway.

hi,

i think that very good random is not required. in our case we don't have large scale RTP conferences with thousands of sources. we have to choose a random number that just differs from the one selected by nanoBTS. (the RTP session will fail afer some seconds when using same SSRC.)
