[Freeswitch-users] Dropped calls on transfer

Sorry Anthony, I didn't see it - it was getting late last night.

I've read it now.


How large are these logs going to get?  We're running on ISDN with calls coming in practically every minute.  At the moment the "freeswitch.log" per day is over 20MB (it rotates the log every 10MB).

Did you not see my last email?

Thanks for a reply, Brian.


That's what I told them they should be doing but they won't listen.  I cringe when I overhear someone saying "call straight through" (ie, "I've pressed xfer twice")  ;)

Looking at the logs when it happens it would appear that a hangup request came from the phone and not the PBX, does that sound right?


Maybe this will help from my debugging last week during a transfer: -

Also had one report of it dropping a call after taking a call off-hold but no more.


Jira?  Sorry what is that?

If your users want to do that they should be doing a blind transfer (Users are hard to train).   Collect data, use latest git, open jira.

Hello,

We've recently switched from Asterisk to FreeSwitch and experiencing a minor problem.


Currently we've got twenty LinkSys/Cisco phones (12x SPA942, 6x SPA962, and 2x SPA504) and experiencing dropped calls when transferring calls.

This seems to happen more often when the caller has hit the xfer button for the second time before the callee has even answered the phone.  But sometimes drops no more than one call a day if the caller waits until the callee has answered.

*          All phones are running the latest firmware (v6) and have been factory reset
*          FreeSwitch is running on version "1.0.head (git-b9b7266 2012-02-10 12-23-58 -0600)"
*          RTP packet size has been changed to 0.020 as per wiki for all phones


Has anyone got any ideas?
