Hi,
I am trying to find a way to add the following info in CDRs (with
asterisk 1.4.23.1):
1. Codec used
2. RTP QoS statistics
3. RTP IP of remote host
4. For answered calls, the peer that requested to end the conversation
I have managed to get 1 and 2 for the caller, like that:
exten => h,1,Set(CDR(userfield)=RIP=${SIPCHANINFO(recvip)}
Codec=${CHANNEL(audioreadformat)}/${CHANNEL(audiowriteformat)}/${CHANNEL(audionativeformat)}/${SIPCHANINFO(t38passthrough)}
QOS=${RTPAUDIOQOS})
The problems I have so far:
*1. CODEC
*Codec is reported only for A-Leg.
When transcoding asterisk logs the above line as: slin for read / slin
for write / the codec of A-Leg / 0 for t.38.
Is there a way to get the codec for both legs of a call?
*2. RTP Qos is reported only for A-Leg.
*Also, asterisk seems to ignore the RTP statistics reports by B-Leg
after the BYE:

These SIP messages are being exchanged after the dialplan has executed
the h extension.
Is there a way to have RTP statistics for both legs?
*3. RTP IP is not reported anywhere.
*The RIP= variable I have above, reports the SIP IP, and again only for
A-Leg.
Is it possible to find out the RTP (not SIP) IPs for both legs?
*4. Find out who hangedup an answered call.
*I have not found any way to determine the peer that requested to hangup
the call.
Is it possible to find who of the two legs requested the hangup?
Any help is appreciated.
Costa
