Grandstream UCM6102 PBX

Postby QBZappy » 02/13/2016

I made some effort to find these settings that worked with Freephoneline. I thought I would share with others who might find it usefull. These are the minimum configuration settings need to make incoming/outgoing calls (that worked for me).

PBX >> Basic/Call Routes >> VoIP Trunks
Host Name: voip4.freephoneline.ca:6060 (Used this one as per Freephoneline, note use port#) Other domains might work just as well
Basic Settings:
NAT: NOT Checked
Username*: 15145551212
Password*: (Whatever)

Advanced Settings:
Codec Preference: PCMU & G.729 (Only codecs permitted)
Send PPI Header: Checked <<-- NOTE (This is the magic setting which made all the difference!!!) Uncheck it to see what happens.

PBX >> SIP Settings >> Misc
Register Timeout: 120 (As per Freephoneline FAQ)
Register Attempts: 0

PBX >> SIP Settings >> NAT
External Host: "DDNS Name:port# of UCM"
Use IP address in SDP: Checked

I added other settings which made no difference to add or remove the ability to make/receive outbound/inbound calls.

These settings populated or not add no value to above configuration.
Send PAI Header:
Outbound Proxy Support:
Enable Qualify:

Additional Notes:
Router Model: Asus RT-N16 (Firmware TomatoRAF)
No portforwarding on router
No sip ALG in router just in case

Thank you for that information (though I realize it was from a while back. I'm struggling with a Grandstream UCM 6202 and am hoping someone can help me with the settings. I moved outside of Canada and it would be great if I could get this working for family to easily call.

Does anyone out there have UCM 62xx settings? What I have so far, are below.
