[asterisk-users] sip_write warning when executing Pickup of CAPI

2006-12-05 Thread Tom Fanning 
I'm trying to pick up a ringing SIP phone (203) across the office with

 

exten = *9,1,Pickup(783743)

 

where 783743 is the local part of the number that our ISDN works on.

 

I tried all of these first:

exten = *9,1,Pickup(203)

exten = *9,1,Pickup(SIP/203)

exten = *9,1,Pickup([EMAIL PROTECTED])

and got a declined message back from my phone (snom 300), so I then
switched to picking up the ringing ISDN line (it's BT ISDN2e on a pair of
Eicon Diva BRI-2M cards)

 

The Pickup(783743) works (the phone across the room stops ringing), but the
calling party gets a nasty distorted noise back down the phone, and I get
dozens of these messages:

 

Dec  5 11:37:50 WARNING[26972]: chan_sip.c:2561 sip_write: Asked to transmit
frame type 64, while native formats is 4 (read/write = 64/64)

 

Any ideas what I'm doing wrong? Asterisk is 1.2.11 on Debian with
2.6.8-2-686 kernel.

 

Thanks

Tom

This sounds like a bug in Asterisk. chan-capi only accepts one format (alaw 
or ulaw), which is configured as native format.
Asterisk here sends frames of type 64 (SLINEAR), which is wrong and not 
accepted by chan-capi.
I cannot tell why Asterisk is doing that.
