Our VoIP service provider routes calls based upon the To field within
the SIP header. While SER can easily rewrite the URI, I need to
actually prepend a digit string (account code) to every outgoing call
with a prefix. Does anyone know how to prefix the To field ?
Well, in our company we just lease all equipment. Yes granted we try
hard to keep the cost down, we figure the equipment cost is the least of
our worries. Now that doesn't mean we'd spend millions on a softswitch,
we're still a small company. :-) A layer7 switch, if you compare the
price to a softswitch, isn't that much money. The only reason we would
consider a hardware solution though at this point is because there is
literally nothing (free) software wise out there.
What we're really wanting it for is Asterisk, since asterisk doesn't
have the ability to do SRV lookups the only other alternative is
butchering the dialplan/making a script to perform redundancy to peer
with SER. With SER I was assuming use of SRV records otherwise, and for
our registered users we would again use SRV records (UA compatibility
pending :D) and hope t_replicate can perform adequately enough.
We have an SRV bounty for Asterisk, it isn't publicly posted, if anyone
is interested ;-) No one stepped up to the plate yet in the ast lists.

So, you found the budget? Or was the pain just big enough... Let's see
what we can do. It will take some time, I assume, so meanwhile...

Gcc,
When dealing with NATed SIP clients you have to handle their RTP (aka, audio
and/or video) in a special manner. The reason is that the two SIP UAs in the
call cannot directly talk to each other.
SER offers two solutions namely rtpproxy and mediaproxy. These are complete
independent of each other and both have pros and cons.
You can run either of these proxies on physically different servers from
SER. So to answer your first question, yes this is a good way. It's not
necessarily a good thing to run these media proxies on the same physical
server as SER, but nonetheless it's better than no audio.
To answer your question about video, the answer, AFAIK, is yes. Both
rtpproxy and mediaproxy support streaming video. I've never tried video, but
there should be nothing special to do. If you search the serusers mailing
list archives you'll likely find other postings related to video.
Regards,
Paul

Hi list,
I'm running ser-0.9.0.
I've come across a strange behaviour of adding new aliases to user names.
I add an alias with serctl command, but the alias wont store in the mysql
table. If I try it again I get error: <sip:joe@mydomain.com>;q=1;expires=-268
Once I restart SER I can again add the alias, but with same result,
it's not saved in the table 'aliases'.
Have anybody come across this issue?
Thank you,
Lada
Hi all,
Here is my confusion about SER supporting NAT transversal.
1. With only RTPProxy, what kinds of types of NAT can SER with nathelper
transverse?
2. What's the difference between MediaProxy and RTPProxy?
3. If UA supports STUN, do SER need to configure nathelper to support NAT
transversal? Just because I knew STUN protocol only process a few kinds of
types of NAT, I want to know what advantage it will add if I configure SER
with nathelper.
Thanks a lot!
