[asterisk-users] ERROR[1499]: rtp.c:2482 ast_rtcp_write_sr: RTCP SR transmission error

[jonas kellens]

Hello list !

SETUP :
Grandstream --sip--> Local Asterisk (NSLU) --iax--> Hosted Asterisk
(VirtualDedicatedServer) --sip--> SIPprovider --> my CellPhone

PROBLEM :
I've noticed that when I put down the horn of my Grandstream it still
takes a while for my GSM/CellPhone to stop ringing.

INFORMATION :
This is the output on the CLI of the local Asterisk-server :

[Oct  3 17:40:33]     -- Executing [0473775006 at intern:1]
NoOp("SIP/nslu-00181d90", "Call to gsm-number") in new stack
[Oct  3 17:40:33]     -- Executing [0473775006 at intern:2]
Dial("SIP/nslu-00181d90", "IAX2/hostedasterisk/0473775006") in new stack
[Oct  3 17:40:33]     -- Called hostedasterisk/0473775006
[Oct  3 17:40:33]     -- Call accepted by XX.31.XX.XX (format alaw)
[Oct  3 17:40:33]     -- Format for call is alaw
[Oct  3 17:40:39]     -- IAX2/hostedasterisk-9480 is making progress
passing it to SIP/nslu-00181d90
[Oct  3 17:40:47]     -- Hungup 'IAX2/hostedasterisk-9480'
[Oct  3 17:40:47]   == Spawn extension (intern, 0473775006, 2) exited
non-zero on 'SIP/nslu-00181d90'

This is the output on the CLI of the Asterisk-server in the datacenter :

[Oct  3 17:40:55]     -- Accepting AUTHENTICATED call from XX.22.XX.XX:
       > requested format = alaw,
       > requested prefs = disabled,

       > priority = reqonly

transmission error to 8X.1X.XX.XX:14129, rtcp halted Operation not
permitted

QUESTIONS :

1. what is this RTCP SR transmission error ???

2. You can notice that the local server detects the 'hungup' @ 17:40:47
and the Asterisk-server in the datacenter @ 17:41:15. There's a lot of
time between the moment that I put down the horn of the Grandstream and
the moment that my CellPhone stops ringing.
Is the delay due to the RTCP SR transmission error ???


Greetingz,
Jonas.
