I have a case open with support... tmm will be fixed to throw an error instead of crashing. To solve my initial issue I am using SIP::uri which works quite elegantly.

 

 

when RULE_INIT {

 

set vs_ip 172.16.10.5

 

}

 

 

when SIP_REQUEST_SEND {

 

 

set my_ip_map [list $vs_ip [LB::server addr]]

 

log local0. "Current uri: [SIP::uri] "

 

set new_uri [string map $my_ip_map [SIP::uri] ]

 

SIP::uri $new_uri

 

log local0. "New uri: [SIP::uri]"

 

}
