Hi Forums,

I’ve got someone else’s box doing strange lockups. It always seems to occur in the logs around a bunch of DTMF transfers.

It is a busy box with a 100+ extensions, so there’s quite a bunch of people getting pissed off when it happens :smile:

Is it a known problem?

We’ve resorted to DTMF transfers because using SIP transfers from the handset (all snom), sometimes a call will get music-on-hold out of the blue midway through a conversation - after the transfer has already finished.

Known problem?
