Hi,
I am new to this, native german so please forgive my mistakes.

I just set up
1. elastix with
a. working sip-trunk (using sipgate.de in germany)
b. working extension

inbound / outbound works perfectly

2. kamailio / opensips-server
a. sip-trunk on elastix, connecting elastix with kamailio.
b.

now I want to configure elastix to pass incoming calls on the sipgate-trunk directly to
the kamailio-trunk.

goal: using the elastix system for the trunk-connection / PSTN-connection, then using kamailio for extension-provisioning.

so, how do I set up call-routing from one trunk to the other ?

I found something of a custom extension with a trunk as destination... but how excatly do I set that up ?
thanks in advance
lutz

What you need to do is make your sip trunk context "from-trunk-custom".
Nest go tp your /etc/asterisk/extensions_custom.conf

you can add these lines
[from-trunk-custom]
exten => _XXX!,1,Dial(sip/your-trunk-to opensips/${EXTEN})
exten => _X!,n,Goto(from-trunk,${EXTEN},1)

the _XXX depend on your DID number your are getting from sipgate ,

but why do you want to use sipgate? Elastix can provision your phones perfectly.

first of all thanks for the help.
regarding your question:
sipgate is for the first tests.
later on I will connect the elastix installation to the PSTN using a SIP-trunk
connecting to a TRansit-partner (providing media-gateway-functions). I am not planning on installing PRI / BRI interfaces or connections into the elastix-box.

anyways back to the question..
so... I need to change what trunk exactly ?
1. trunk to sipgate
2. trunk to kamailio

is it possible to set up this parameters so that every DID in a certain range (ex. 123400-123455 gets passed on like that ?

thanks again
regards
