[SR-Users] Problem with callid as htable key

[Daniel-Constantin Mierla]

Hello,

the expression in the $shtcn(table=>exp) can have some operators at the
beginning, see:

  -
https://www.kamailio.org/wiki/cookbooks/devel/pseudovariables#shtcn_htable_exp

So, eq is one of them, the safest is to explicitly set the operator if
you cannot predict what is the key, like in this case. If the operator
is missing, then the exp is matched as regular expression, so you can do:

$shtcn(ht_test=>~~$var(htid))

Cheers,
Daniel
