ER605 SIP registartion failur
Hey Guys,
Couple of days ago I replace my exsiting router ( TP-link 1600V) with ER605. Everything is fine except my PBX SIP registration fails. I have contacted the SIP provider and they advised they are not getting any registration attempt at their end. Searchin online, it seems link this was a know issue with TL-ER6020 which very simiilar to ER605

ER605 <--- Internet ---> CISCO UC320W
when I replace the ER605 with an old modem, it works just fine. I haev disbaled the SIP ALG as per SIP provider
Hope someone can help!
Thanks
