Nextiva VOIP Issues (Bad call quality)

RouterOS General
1

Hey!

So I started to use Nextiva VOIP in my office and I’m having issues with call quality and it breaks up a lot. The configuration sent to me by Nextiva is the one on the photo

The biggest issue is that I do not see a difference or packets running through those IPs. SIP ALG is disabled since Nextiva doesn’t use it.

Can anyone tell me what could be wrong with this?

Here is what I put in this morning.

######### Set the Phone Address List to Match Your Phone IP Scope ##########
############################################################################
################ Open New Terminal and Paste this code in ##################
#### After Import... Locate the Phone list in /ip firewall address-list ####
############ Correct it to the IP scope of your phone subnet ###############
#### Move the Nextiva Rules to the Proper Spot in your Firewall Filter #####
############################## That's It ###################################

/ip firewall service-port
set sip disabled=yes
/ip firewall address-list
add address=192.168.76.0/24 list=Phones
add address=208.73.144.0/21 list=NextivaServers
add address=208.89.108.0/22 list=NextivaServers
/ip firewall filter
add action=accept chain=forward comment="Nextiva Rule" dst-address-list=\
    NextivaServers src-address-list=Phones
add action=accept chain=forward comment="Nextiva Rule" dst-address-list=Phones \
    src-address-list=NextivaServers

I created the rules but calls still break up a lot. Not every single call though. I made 3 calls externally and 1 of them broke up a lot. It also says to open ports 5062 to 5090.

I also got these 2 pieces of info from a test on Nextiva’s site.

Hope this info helps to diagnose this issue.

Thanks for the help!
