GDMS voicemail access Number


First of GDMS is awesome! it just made my life that mush easier. Now I cant find anywhere in the GDMS to add voice mail settings like *97 to dial voicemail from GXP21xx, WP820 and others. If I were to use config it would be P33=*97 but I don’t see that setting in the GDMS. IS it missing?


No, it’s under SIP Server. Check it out.


Yup! thank you very much.


Dear user,

Thank you for using GDMS platform! P33 (Voicemail Access Number) configuration option is under SIP Server configuration page, not in each device’s Set Parameters module. Thanks for your testing!

Thank you!


I really appreciate this provisioning platform, it just works. I have so far 15 grandstream device across 2 organization and I haven’t had any issues. I have done complete factory reset on several phones and it restores all settings including vpn certs on all devices. This makes managing devices remotely easy.

Sorry ! didn’t mean to derail this topic.
