Has anyone set up a GSM Gateway who can offer me some advice.
I have a Sun Comm SC-385 GSM Gateway but the instructions are not clear at all. I cant work out how to get my FreePBX to see it as an outgoing trunk.
The manual is broken english and leads me to think I have two options, either to set up extentions which the GSM box logs into or to set up some LAN to GSM routes.
Unfortunately I am not sure how Asterisk sees either.
I only want to use this for outgoing calls.
Any pointers no matter how minor would be helpful.
Using FreePBX 2.8 & Asteris 1.8
I now have one trunk running and am attempting to set up a second trunk to take advantage of the second SIM. If anyon can offer advice here I would be grateful.
Once I have this running I will post information on how to set these up for future users.
I have now set up a SIP Trunk, which I am using for outbound.
My Peer details are set as:
My GSM box is set to send everything outside.
When making a call I get:
Receiving Phone - Rings
Calling Phone - No Ringing Tone
On Answer - there is no audio and after about 30 seconds the calling phone gives the message “All Circuits are busy now” - “The person you are calling is unavailable.”
It seems that the GSM box is not telling the VOIP that the call has been made.
Any ideas where to look.?
I am guessing that I tell the trunk the IP through the ‘custom string’ can you advise if this is the case and if so, what are the options in from of the @ sign.
No the dial string goes in the custom string.
The trunk host statement defines the IP of the peer.
I have been trying to connect via setting up a custom trunk. I had put in the custom string SIP/[email protected] The GSM box is set up to put anything from my server IP to the network.
- This made the call but there was no audio.
I will try again but this time I will create a SIP trunk. - Any advise on username password etc as the GSM box doesnt seem to have one (or is this wht I set to ‘friend’?
Sorry for the dumb questions, this dealing with contexts etc is all new stuff.
I would start with a simple trunk that only contains the IP of the gateway, type=friend, insecure=very (or in 1.6 port,invite), context=from-internal and the CODEC you want to use. That will allow communication both ways.
