You can do this by setting PJSIP_MAX_PKT_LEN in your config_site.h. And you'll need to enlarge the log buffer size too to accommodate the larger packet, so probably you'll want something like this in your config_site.h: #define PJSIP_MAX_PKT_LEN 4000 #define PJ_LOG_MAX_SIZE 4000 cheers, -benny > Thanks in advance, > Matti Zemack, BBC R&I, Kingswood
