Hi,

Hi, Yes, I've started to clean up the headers from cisco, but I do agree that som generic "compression" function wuld be nice to have. As long as all crucial information is kept.

compression without any loss :)

Is there really a way to use compact format withing the script (without regexp textops)?

guess right now the only way is to use subst() from textops :(

Hi Helge,

if you have problems on client side with UDP fragmentation, there are two ways to go:

1. try to reduce the size of the message; CISCO sends a lot of

useless stuff in the requests; first option will be get rid of useless headers; second to use short format for hdrs with long names (can be done from script); third to merge headers of same type (VIA, contact, route) to get rid of extra hdr names (cannot be done from script). 2) switch on TCP, but more complex problem can pop up - maintaining TCP connection to UAC from behind NAT, extra load does TCP conns manipulation, more size in packages due double RR (due protocol switch), etc...

maybe a "compacting function" will be useful to have - it will do 1) second and third option: if(msg_len>UDP_frag) compact_msg();

regards, bodgan

Hi, I've just had my first fragmentation problem. Since I'm using rr on my dispatchers and my proxies, INVITES from a gateway (i.e cisco) gets too large and are being fragmented...and of course not very good for nat'ed udp clients.

Are there any other options than to remove_hf of less important headers like Remote-Party-ID and/or User-Agent?

I guess TCP would be an option....
