Hi all,
I am Jose Saldana, a researcher from University of Zaragoza, in Spain. I am new in this list! In our research group we are working on a small-packet grouping solution, which may be of interest for "call trunking" between two Asterisks. I know that IAX2 supports trunking, but some Asterisk's users prefer SIP+RTP for different reasons. Therefore, including an "RTP trunking" solution in Asterisk could be an interesting feature. The name of our proposal is Simplemux. We have proposed it to the IETF, and we also have a running implementation. The savings can be huge (up to 50% for certain voice codecs), as multiplexing is combined with ROHC header compression. If the Developers team find it interesting, I think it could be easily integrated into Asterisk.
