Tengo un SPA9000 y un SPA400 conectados a varios SPA9xx y a 3 SPA504g, el problema que tengo es cuando entra una llamada PSTN,

esta llamada la recibe un SPA942, al transferir la llamada a cualquiera de los SPA504g, el telefono  se congela y solamente desconectandolo

vuelve a la normalidad, esto sucede aleatoriamente, de 6 llamadas 2 a 3 fallan. Esto no sucede con los telefonos SPA9xx.

Mucho agradecere su ayuda.

Are the phones running the latest software?  What happens when transfer from 50x to 90x phone?

Do you happen to have a log or trace of this?

The phones are running the following version:


When I transfer from 50x to 90x, everything it's ok.

Attached a syslog trace, please let me know if you need something else. ---> SPA9000 ---> SPA400 ---> SPA9000 remote office ---> SPA9000 remote office ---> SPA400   remote office   ---> SPA504g

The 6 MB log contains a bunch of registration and notify messages, mostly with spa9000 and spa400.

Since you have remote offices, does this transfer problem occur with calls between offices and/or with calls within just the local office?

It would also help to upgrade your 50x to 7.4.4 located on

For the log, just turn it on in the 50x phone.  Set the SIP debug option to full excl opt|ntfy|reg.

The slogsrv program has an option to put in timestamp, it's slogsrv -t, this would add timestamps and parse the syslog header.  This way, you can tell me what time the issue occured and I can look for it in the log based on time.
