Ok, more or less solved:

I've coded a queue based on an Array of fixed length (5000 entries as max 
size). When a message is extracted from the mqueue is appended to the Array. 
When the corresponding SIP message is sent (by other thread) such entry is 
shifted from the Array.

I get same performance than using Posix mqueue as queue, but now the mqueue 
just requires maxmsg=100 which is much less than 5000 :)
