Portech mv-374 register again and again

Hi everybody

Do you know what could bring this GSM gateway to register many time by minute? I’ve already ran through this problem with a Ip phone. I solved this by putting srvlookup=no in sip.conf. But this time, it don’t work and I don’t kno why. What can I do?

Thanx for giving me your attention.

I have problems configuring mv-374 too with freepbx can you help me with this. And than I will try to help resolve your problem :slight_smile:

You surely are a great businessman :-). Ok, What’s your problem?

In SIP Settings/Other Settings
