[OpenSIPS-Users] remove function not working for specific contact

[Jayesh Nambiar]

Hi,
Alright, can someone please confirm if remove function in registrar module
works as expected. If my UL SHOW shows this, what should be used to remove
this particular contact only form the location:
ecef74d17522a634b0412c at abc.com
Contact:: sip:ecef74d17522a634b0412c at 11.22.33.44:54332;rinstance=ca9915acb1b3e3a1;transport=tls
Q=
Expires:: 137
Callid:: YTdlZjVjNzMxYTg1ZWI5ZTZkMDgzODJiYmMyZjA5MzQ.
Cseq:: 1
User-agent:: v2.0beta_ios
Path:: <sip:44.33.22.11:7300;lr>
State:: CS_NEW
Flags:: 0
Cflags:: 30
Socket:: udp:55.66.77.88:7300
Methods:: 1391

I assumed it to be remove("location", "cef74d17522a634b0412c at abc.com", "
sip:ecef74d17522a634b0412c at 11.22.33.44:54332")
I tried this but didn't work. If this is correct I'll log and check if this
is exactly what I'm passing to the remove function and check whats wrong.

Thanks,
- Jayesh
