Slight 8 second delay to hear ringback tone

Post by Track221 »

Im using the HT702 Grandstream device, my router is a linksys e4200v2, Basically everything works for my voip configuration except there is one slight problem, when finishing punching in a number i hear an 8 second silence then i hear the ringback tone, shouldnt the ringback tone be heard right away upon finish entering the number? IS there a setting on my HT702 that i can set to fix this problem?

I often have the same issue with Grandstream HT701. And even, sometimes I do not hear any ringing until the call is answered.

Hi there,

Please login into your E4200 and check if SIP alg is enabled. Also, if you made a DHCP reservation for your HT702- please remove it.

Please try and let me know.

Thanks,
