Hello! I’m confounded by setting up a working route for E911 on my Freepbx/Obi202 system. I’ve configured 3 gv trunks and outbound routes, and a single extension line attached to Line 1 of the obi202, according to notes found posted by twosortoftechguys. It’s a great aid for Obi device users with freepbx.
I’ve subscribed to gv911com, and tried their configuration, replacing with this string on the obi202 at ITSP Profile A/DigitMap:
I’ve added an Emergency enabled outbound route on Freepbx at the top of the list with 911 and 922 entries, along with 911, 922 entries with trunk-specific prepends (**1, etc.).
These steps didn’t work, causing only CONGESTION errors on the pbx extensions, and a busy signal on Line 1 of the obi202.
I found other notes on this problem suggesting creation of User Defined DigitMaps on the obi202 , so tried it with these:
Name is: gvTestE911 String is: (<922S0:14242798235>)
Name is: gv911E911 String is: (<911S0:14242798234>) (these are the test and 911 relay numbers from the service)
…and then, according to those notes added this in front of the string at Physical Interfaces/Phone1 Port/OutboundCallRoute: (!Particularly note the ‘M’ when added to the DigitMap name!)
…making the entry this, in full:
!! The above changes on the Obi202 did enable a good 922 test from gv911, BUT ONLY ON THE OBI PHONE LINE !!
The 922 test now results in a BUSY instead of CONGESTION from the other Freepbx extensions.
I’m pretty sure my problem is in my Freepbx Outbound Routes somehow, but I haven’t a clue what. Any guidance would be VERY appreciated, and once solved I intend to write this up as a tech blog post on the subject for others using the same set up. It’s a frustrating problem… Thanks again for any assistance!
