[Devel] OpenSER sometimes goes down.

[Bogdan-Andrei Iancu]

Hi Derek,

according to the RFC 3261 URI syntax, I understand that the parameters 
values cannot be placed inside quotes. Here are the relevant rules:

uri-parameters    =  *( ";" uri-parameter)
uri-parameter     =  transport-param / user-param / method-param
                     / ttl-param / maddr-param / lr-param / other-param
other-param       =  pname [ "=" pvalue ]
pname             =  1*paramchar
pvalue            =  1*paramchar
paramchar         =  param-unreserved / unreserved / escaped
param-unreserved  =  "[" / "]" / "/" / ":" / "&" / "+" / "$"


It seams to me that the value is just an array of chars.

Regards,
Bogdan
