[asterisk-users] Asterisk 1.6 - Problems with SIP/REFER

I am having issues with transfers (SIP/REFER) using Asterisk 1.6. You will find the SIP debug below.
There are three phones in this setup. 5253 and 5258 are Aastra 53i telephones, 101 is a standard phone connected through an Audiocodes gateway. All phones are registered in context "phones" and are set to not allow reinvites. All phones can dial each other directly. The dialplan looks as follows:
[phones]
Exten => 5253,1,Dial(SIP/5253,10)
Exten => 5878,1,Dial(SIP/5878,10)
Exten => 101,1,Dial(SIP/101 at audiocodes,10)
Transfer fails regardless of the order (101 calls 5878, 5878 transfers to 5253 or 5878 calls 5253, 5253 transfers to 101, etc)
I do not understand the message "Spawn Extension (phones, 101, 0) exited non-zero" in the debug - there is no "priority zero" in a dialplan - priority should start at 1. What is this message telling me?
What do I need to do to allow these phones to transfer calls between each other? Any help is greatly appreciated!
Here is the debug:
*CLI> == Using SIP RTP CoS mark 5
== Using UDPTL CoS mark 5
-- Executing [5878 at phones:1] Dial("SIP/5253-0823eab0", "SIP/5878") in new stack
