Arris TM804 eMTA MGCP protocol error

Asterisk Asterisk Support
1

Hi,

I’m doing a basic PacketCable 1.0 setup with NCS call signaling.
I use Arris TM804 eMTAs and Asterisk as CMS.
When the call is answered the eMTA responds to MDCX message from CMS with “Protocol error 510”.

My mgcp.conf:

[general]
port = 2427
bindaddr = 0.0.0.0

tos=cs3         ; Sets TOS for signaling packets.
tos_audio=ef            ; Sets TOS for RTP audio packets.
cos=3                   ; Sets 802.1p priority for signaling packets.
cos_audio=5             ; Sets 802.1p priority for RTP audio packets.

firstdigittimeout = 30000 ; default 16000 = 16s
gendigittimeout = 10000   ; default  8000 = 8s
matchdigittimeout = 5000  ; defaults 3000 = 3s

[mta001dd027b7cc.pktcdm]

dtmfmode    = rfc2833

ncs         = yes ; Use NCS 1.0 signalling
pktcgatealloc = yes ; Allocate DQOS gate on CMTS

wcardep = aaln/*        ; enables wildcard endpoint and sets it to 'aaln/*'
callerid    = 8001 <8001>
accountcode = arris1-8001

line        = aaln/2

Here is my eMTA config:

Main

MtaConfigDelimiter 1;

MtaConfigDelimiter 255;
}

Here is the screenshot of Wireshark capture of MGCP messaging between CMS and eMTA during an incoming call.

Frames 8 and 10 are the MDCX message and the response.

Does anyone what might be the problem here?

Thanks.
