Does your cients have random phone numbers or are they all in the same
block? IF you have a numer block, e.g. 321XXXX, just use
if (uri=~"^sip:321[0-9][0-9][0-9][0-9]")
lookup(location)
....
else
forward to PSTN
If the internal numbers are random, you can use e.g. a second location
table (let's call it location2). It will have the same structure as the
location (or alias) table and you have to enter every client, and using
its local account as contact (so lookups will not change the request-uri)
then the proxy could do:
if (lookup("location2")) {
user is a local user
if (lookup("location")) {
#user is online
t_relay()
} else {
sl_send_reply("404","offline");
}
else {
#no local client
t_relay_to_tcp("gateway-ip");
}
If someone knows an easier solution I'm pleased to hear it.

Hi,
I'd like to use official phone numbers inside my voip network (the
numbers are assigned to me and are routed to my Cisco-5300 gateway in
case of an incoming call from PSTN), and I don't want to use a prefix
when calling from voip to PSTN.
Now when I want to perform a call from the voip net, how can I decide
wether it's an internal voip call or should be routed to the PSTN gateway?
Would it be a proper solution to just lookup in the aliases- and
location-table, and, if not found there, just forward it to the PSTN
gateway? The PSTN gateway should then route it back to my SER if it's a
number assigned to me, and I'd get a loop, which should be detected by
the mf_process_maxfwd_header() function.
Sounds like a ugly hack, and I'm really not shure if this would work, so
how would be the standard solution for such a task? (beside using a PSTN
prefix)
Regards,
Andy
