Hi, you should use TCP instead of UDP in the case of big messages like presence notifications...

I think that something about this is written in SIP RFC (3261).

Hi All,

I am experiencing a problem in receiving the NOTIFY messages on my client. If the message size is less then 1 KB then it is getting delivered but not more then that. For that I changed my max_len settings in ser.cfg as given below to 15000.

    if (msg:len >=  15000) {
            sl_send_reply("513", "Message too big");
            break;
    };

But now the messages are getting delivered when I am trying to send it over my local network but when I send it over GPRS, It keeps trying to send the message for some time and timeout after some time.

I am using ser 0.9.6. Please let me know if you have any suggestion to solve this problem.

Regards, Gourav
