How to (or how I did): Sending 911 (or x11) calls from one Obi to another (-110)

<< < (3/3)

user17600:
Okay, after a lot of experimentation, I can get the -202 to direct-IP the -101 and to send x11 to the {li} port.

These are the changes made:

1) On the -202, set speedcall 5 to SP3(611@1.2.3.100:5061)

Note: 611 is my test number; once I have all the issues solved (see below), I'll swap out 911 and disable the Obitalk methodology above)

2) On the -202, set the SP3 Calling Features CALLERIDNAME field to some recognizable name.  Let's say NAME_202

Note: SP3 is an active SIP account (sipsorcery in this case)

3) Because I'm sending the call to port 5061, this will come in on SP2 on the -101.  Therefore on SP2 on the -101, add {('NAME_202')>(Mli):li}, to the X_INBOUNDCALLROUTE

Note: the single quotes are critical if the name has a special/reserved character in it.  See page 180 of the Obi Admin Guide.  This oversight haunted me iand could have been avoided if I'd just used the Obinumber in that field.

Quote: m, M, s, S, x, X which have special meaning in the digit map syntax

Otherwise (in the end) I made no changes other than those described in my original post (at least that made a note of).  The two changes are compatible the way I have them set up now (via Obitalk and direct-IP via speedcall).

HERE'S THE PROBLEM:  while I can get the -202 to dial out via the -101 {li} port, I HAVE NO AUDIO ON THE -202.  I can pick up the phone line connected to the NID (not connected to either Obi) and hear the 611 menu, but can hear nothing on the -202.  And the -202 cannot send tones, so this is apparently a 2-way problem.

I have reviewed many of the reports of no audio on the forums and elsewhere, have tried some port forwarding and the like, without success.  Because both units are inside the firewall, nothing should be blocked, so I'm let scratching my head.

For those that have done direct-IP calling, how did you work-around the no-audio issue (if you had it at all)?

I'm nearly there but need to crack this audio nut.

Thanks for everyone's insight.

user17600,

It may not be the cause however something to try.

Audio issues are sometimes related to the codec used. Have a look on the Call status of both units in a call. You will be able to see what voice codecs both units are attempting to use. Try forcing the codec to G711U Codec by disabling all other the other codecs.

user17600:
Both showing g711u during the call.  Of note, the -202 is transmitting packets, but the -110 is not receiving them and vice versa.  So beyond the transmitting the x11 number, no packets are being exchanged.

Even tried to specify the RTP port as part of the @1.2.3.100:5061 --rtp-port=61000 (and 16XXX series) without success.

Thanks for the idea, tho.

user17600:
Hmm, no one using direct-IP calling has "no-audio" experiences?
