SPA504G: Syslog-Msg [0]CC:NewCallState 0/9


during a phone call I see several syslog message of the form

[0]CC:NewCallState 0/9

Which call states does exist?  I would expect the number inside the brackets encode somehow the used extension and the line - but how? Or does it encode something completely different?

Thanks in advance!

Note, I have no documentation related to it - this is unauthorized answer based on observations.


[x]CC:NewCallState M/N   is message from "CallControl"; x is call index (no more information about it), M is brand new call state, N is previous call state

Recognized Call States:


| 00 | CC_CST_IDLE       | Idle

| 06 | CC_CST_DIALING    | off-hook, collecting user input

| 08 | CC_CST_CALLING    | calling

| 09 | CC_CST_PROCEEDING | other side ringing (outgoing call)

| 10 | CC_CST_RINGING    | Ringing (incomming call)

| 11 | CC_CST_INVALID    | ending (audio channel released, call ending)

| 12 | CC_CST_ANSWERING  | answering (ringing phone picked up)

| 13 | CC_CST_CONNECTED  | connected (audio path active)

| 14 | CC_CST_HOLD       | on hold

| 15 | CC_CST_HOLDING    | going on hold

| 16 | CC_CST_RESUMING   | resuming


Common sequences

Call, originating phone: 0->6->8->9->13->(parties talking)->11->0

Call, answering phone: 0->10->12->13->(parties talking)->11->0

Edited by: Dan Lukes, call state symbolic names added (used by SPA1x2 devices in place of numeric codes used by SPA50xG devices)

Hi Dan,

Nice work on putting together the call states table. I ran your table past a development engineer and they said that the [x] in the [x]CC:NewCallState M/N syslog/debug output "is the call appearance index and is useful for when development engineering is tracing the call object".
