Hello,
Kamailio is crashing when I'm trying to set the parameter;
`modparam("tm|usrloc", "xavp_contact", "ulattrs")
`
The crash is happening when I'm register 2 devices with the same extension.
This is the core dump:
#### Reproduction
Set the following parameter:
`modparam("tm|usrloc", "xavp_contact", "ulattrs")
`
and register the same extension from 2 different devices. Then send an message to them
(NOTIFY/OPTION/INVITE etc)
