Capturing streams with wireshark during phone conversations between 
softphones and pstn subscriber, I can see all sent and received RTP packets 
are 214 bytes long, as in Linphone as in Ekiga, with 20 ms *mean* interval. 
But there is a difference between the two softphones: While Ekiga sents one 
packet every 20 ms without exception (as long as I can see), Linphone sents 
almost always two packets in the same millisecond with 30 or 40 ms 
intervals. One packet with 20 ms interval is the exception.
I don't think this is an inconvenience but I am a few surprised.

(Received packets intervals are always 20 ms +/- jitter.)
