Hi
Cause code 47 is media negotiation error . Have you checked regions between jabber and PSTN gateway ? Are they on different device pool or same device pool? Check codec between these regions

Hi Arunajay

thank you for your replay, i checked the device pool between Jabber and pstn gateway everything seems ok ,

FYI i have the same problem with sip Phones in Branch office .

Best regards

Hi Aek,

the only message that appears in the logs attaches is the outgoing H323 message.

collect the logs before making the call and after making it to see what is going on exactly ....
and let us know the calling , called number and time of the call is good for us to find where is the codec issue exactly.

i think you have an h323 gateway.
debug h225 asn1
debug h245 asn1
debug voip ccapi inout

Hi Aek,

1 Have you checked MRGL on Phones and GW Page: are you using hardware resources or software resources?

2 Is it working before ?

3 Can you please share router config

Nashaatmusa · ‎02-26-2020

So the routing is sending the G711ulaw codec, but getting disconnect directly , we are not at the phase of doing the negotiation and the cause 47 is being sent from the other h323 end..

1) share the configuration of Dial-peer 2 and Dial-peer 17
2) Can you share the CCM traces , or enable the Early offer or fast start hence we get the codec from cucm first

Aek Hem · ‎02-26-2020

please find attached the GW config.

Hi

You are using custom cptone then make sure you are using the correct disconnect frequency and cadence. Invalid values might cause abrupt call disconnect like this.

Try to change on port config for testing.

echo-cancel coverage 64
cptone ?

HI sandip,

just to clarify the problem is with branch office (where SIP phones are connected to LAN through VPN) and jabber phones .otherwise PSTN calls are working fine from other sites.

Nashaatmusa · ‎02-27-2020

the problem is not at the gateway side for sure , the configuration seems good , the dial-peer 2 forces the codec 711u , CUCM is dropping the call, can you try the early offer and share the the CCM traces with us ?

well this shows that the issue in cucm , but still no clue what is the problem exactly as this call logs only shows the top summary of the call flow

we need to collect these logs using this method

What codec(s) are being used by the calls which do work?
