Cannot make outbound SIP calls

[bluesky007]

I cannot make outbound SIP calls using a SIP account on my M9. Anyone else see this behavior.? Sometimes the call goes through my Verizon number and occasionally it errors out..

Enabling/disablign Advanced Calling feature didnt help

Steps to reproduce:

1) I tried keying in a number,

2) Select Internet Call,

3) Select the SIP account (callcentric/localphone etc).

Any ideas/pointers?

thanks for the info, @weth ...

but it's weird they allow inbound SIP but block just outbound SIP??

It seems as if we're blocking this VIA ALG; Here's the link:
