Sample Configuration
System Parameters for 2N VoiceBlue Lite
Set information on the IP interface only ...address, mask, default gateway
SIP Parameters
• SIP proxy (GSM->IP) instructs the gateway where to send the invite packet during a GSM-VoIP incoming call ...the pbxnsip IP-PBX address in this case
• SIP proxy (IP->GSM) instructs the gateway from which IP address the gateway may receive SIP packets ...the pbxnsip IP-PBX address in the case
and this is it for outgoing calls.
Edit GSM Outgoing Groups
Set Delay for CONNECT to 0 (no delay after you answer the call) and Delay for Alerting to 1 (it enables you to hear messages from GSM network or real ringing). Also set CLIR to Factory (called party can see my number)
Edit Network List
Set allowed prefixes in Table of prefixes (prefixes for cell phones) and length of number (9 digit is default length in Czech Rep.)
Edit LCR Table
Assign GSM group and Table of prefixes in LCR table
It should look like this afterwards
and this is the only setup needed for outgoing calls.
Edit GSM Incoming Groups
For incoming calls from GSM, set routing to extension 101 (Extension 101 must be created on the PBX)
Incoming GSM calls are going to ring on extension 101 without answering it in GSM (calling party doesn’t pay for call until extension 101 answers the call).
Configure the pbxnsip side
The example above sends incoming calls from the GSM side to extension 101 on the PBX, so you must create this extension. Next create a 'Gateway' trunk and edit the trunk's configuration per the example below:
All done...
