[asterisk-users] Duplicate channel variables after transfer

with an (attended) transfer i see the following happening:
1) A calls B1
2) B2 calls C
3) B2 transfers call to A
4) A talks to C
At step 3, the channel A is connected to channel C and B1 and B2 are hung up.
In the h extension for channel B2, the channel is renamed to B2<ZOMBIE> and i
see that the channel variables of A have been merged into B2<ZOMBIE>. If there
were duplicate names for variables, the channel now has those variables
doubled. The DumpChan() application called from the h extension confirms this.
In my case the channels are all SIP channels and in the h extension I want to
access the SIPCALLID variable of the A channel. Every access to it gives me
the wrong value namely that of channel B1. How do i access the _second_
variable named SIPCALLID in the channel?
Extract from DumpChan() as an example:
Dumping Info For Channel: SIP/sipout-00000055<ZOMBIE>:
SIPCALLID=eae94252-ebf238ff at 172.28.4.112
SIPCALLID=lyvkqtybsgrtsnh at 172.28.4.113
I want to get lyvkqtybsgrtsnh at 172.28.4.113 instead of eae94252-
ebf238ff at 172.28.4.112 as a result.
