Hi All,

Has anyone seen that something (most likely an alg) on Verizon's LTE/4G 
network is rewriting SIP headers,in particular From Tag identifiers? We 
cannot make a SIP call from our cellphones (using cellular data) beyond 
30 seconds because the TAGs are rewritten and the destination Asterisk 
server drops the call because of this.

Thanks

Mark
