Bill,

I think there is different syntax for this, I used to use something like:

if(len_gt(max_len)) { }

But, I don't check for max length any more. Operating system assembly/disassembly for packets bigger than the mtu is transparent to me, I often work with big packets. Also, the mtu is different depending on where you look. I think some of the gig-ethernets use jumbo packets, then there is the 1500 byte or so regular mtu, then there is also possible modifications to the mtu depending on what the local transport is (cable, dsl, frame relay, etc).

I still check for max hops :-)

OK, I solved the problem(though I don't understand how it solved) by adding alias=" sip.mydomain.com", thanks to my old experience with SER:).

It does not help me here:(. I will get "Too Many Hops" (SIP response 483), it's something that seems to get my SIP message stuck in the first 2 routines.

I have the exact problem. I fixed by changing it to the following instead:

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

Hi,

I've exhausted my knowledge on openser:(. Following is my openser.cfg which is pretty much copy directly from sample but I kept getting "513 Message too big" response from this server for SIP registration, I know the SIP registration message size is ONLY 555 bytes, what could be wrong here?

Thanks in Advance!
