[asterisk-dev] Strange error when sending SMS on Zap

[Julian Lyndon-Smith]

I'm sending an sms message, but on the console I get the following:

  Attempting call on zap/r3/17094009 for application SMS(xxxxxx) (Retry 1)
     -- Requested transfer capability: 0x00 - SPEECH
May 31 15:05:48 NOTICE[31967]: channel.c:2555 __ast_request_and_dial: 
Don't know what to do with control frame 15
        > Channel Zap/2-1 was answered.
        > Launching SMS(xxxxxx) on Zap/2-1

The sms is sent, however.

Anyone know if this is an error or not ?

I sent to the -dev list because I thought that unknown control frames 
were "not a good thing."

Julian.
