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
