3 calls in the past 2 days have dropped anywhere from 1.5 to 4.5mins into the conversation.
We are using a Trixbox with IAX2 trunk to 2talk, recently (forced) to upgrade to 2TalkPlus
Before you unhelpfully reply dissing the trixbox and suggesting some other alternative, it has been working flawlessy for 2-3 years and if it aint broke.. well you know the rest.
The only thing I have changed recently as we used to log in to a 03281XXXX number with the trunk, but I changed it to log in with our 0800 XX XX XX number instead (as the 0800 was just diverting to the 03281XXX number anyway, and the caller ID always showed the source as 03281XXXX which was unhelpful)
other than that the port forwarding is the same, the trixbox IP is the same, and like I say its been near flawless for several years, it seems very unusual.
Ive submitted a ticket to 2talk, and I am expecting a reply before 2014, but if anyone has any ideas id be happy to hear them
