Trouble with Lenny

[dallas]

I have setup a custom extension on my Incredible PBX 4.11.3 for RasPBX. I used the same setting from the Incredible PBX 13.0.192.19 build.
When I dial 53669 from any extension - internal or external - the call to Lenny answers and I can hear him.
When I route an incomming call to extension 53669 the call connects and there is silence.

This is part of the Asterisk CLI for a call from extension 703 to 53669.
-- Executing [s@macro-dial-one:43] Dial("SIP/703-0000008a", "SIP/[email protected],,trI") in new stack
== Using SIP RTP TOS bits 184
== Using SIP RTP CoS mark 5
-- Called SIP/[email protected]
-- SIP/sip2sip.info-0000008b answered SIP/703-0000008a
> 0xb65d8b90 -- Probation passed - setting RTP source address to 192.xxx.xxx.xxx:8000

This is the same part on the CLI for a call arriving on a SIP trunk terminating on 53669.
-- Executing [s@macro-dial-one:43] Dial("SIP/09564350-0000008c", "SIP/[email protected],,tr") in new stack
== Using SIP RTP TOS bits 184
== Using SIP RTP CoS mark 5
-- Called SIP/[email protected]
-- SIP/sip2sip.info-0000008d answered SIP/09564350-0000008c

Any suggestions on where I go from here to resolve this?

I would suggest looking at media reinvite as it sounds like an issue with media redirection/ possible nat issue with audio streams and your incoming trunk provider. I could post the exact changes if needed in a few hours when I get back to my laptop that I had to make.

@dallas Simple solution, but not obvious: Put the Lenny extension (53669) in "Extension List" of a ring group by itself. But, be sure to add a "#" to the extension number in the group, i.e., 53669#

Then, direct the incoming route to the ring group instead of the extension number. Works!

The "#" is needed because the number is considered to be "external" to your PBX.

@frostybtc Thanks. I'd appreciate that.

Thanks Pete, I'll give that a try.

Just wondering if the coded URI is correct as Wards post here

exten => 53669,1,Dial(SIP/[email protected],20,tr)

I assume that URI is still working; but implementation on my Pi uses the host your own version see thread here

Yes it's working. My internal calls to 53669 are ok and tromboned inbound calls connect but there is no audio.
I should investigate making it local.

I wonder if you have reinvite enabled and if there is a codec issue between you and Lenny.

I have always simply setup Lenny as a Custom Extension with
dial = SIP/[email protected]

dialing it direct works fine, a transfer works fine, and even blacklist to Lenny works.

It could be reinvite. It won't be a codec issue as the call connects, there's just no audio. The call will fail if a codec can't be negotiated.
