Voxalot not responding to OPTIONS

Absolutely.
BTW, some time ago Linksys added this option in it's firmware, at least for some models. Initially it was possible to use $OPTIONS or $NOTIFY only, but now it is possible to specify something like "0x0d0a" as NAT Keep Alive Msg:.
Nokia phones are using "0x0d0a" by default as well.

Let us know if this helps?

Hello Martin, thank you for looking into the issue.

So far I came to the following working configuration.
Just a side note - I have to have 2 separate registrations to voxalot as I need 2 "numbers", 1st is "direct" and 2nd is for IVR. Unfortunately voxalot have no support for aliasing Otherwise I will be happy with 2 different numbers pointed to a single registered contact. This means that I already have 2 trunks configured for voxalot.

This is my trunk setup:

1st trunk

host=proxy01.eu1.voxalot.com
defaultuser=xxxxx0
secret=password
type=peer
context=custom-get-did-from-sip
fromuser=xxxxx0
fromdomain=voxalot.com
insecure=invite
qualify=yes
qualifyfreq=120

register string: xxxxx0:password@eu.voxalot.com

2nd trunk

host=proxy02.eu1.voxalot.com
defaultuser=xxxxx2
secret=password
type=peer
context=custom-get-did-from-sip
fromuser=xxxxx0
fromdomain=voxalot.com
insecure=invite
qualify=yes
qualifyfreq=120

register string: xxxxx2:password@eu.voxalot.com
