Strange "from" in Service Indication

Hi,

When I'm sending service indication (WAP-PUSH) through the Kannel to a
phone, then when the message is received in the phone, the sender of the
message appears to be "1234" (I see "from 1234"). I've noticed that it
happens only on Symbian based phones. 

I've tried to look for a configuration in the Kannel to change the
"from" number, but didn't find one. I only find configuration of
"fake-sender" to SMS.

 

Anyone knows how to change it in service-indication notifications?

 

Thanks
