[asterisk-users] SIP Error message

[Thomas Kenyon]

Does anyone know what causes the following error message means.

Aug 29 10:11:08 WARNING[30913]: chan_sip.c:2561 sip_write: Asked to
transmit frame type 256, while native formats is 8 (read/write = 256/256)

I've not yet tracked down what is causing this, but I get a lot of them
at the same time.

It may be related to a nokia E60 trying to pick up the call. (It's hard
to tell atm.)
