Hi all,
The Overview of the Cisco VG310 and Cisco VG320 Voice Gateways on Cisco's website lists the VG310 as being able to support VWIC3-1MFT-T1/E1. Does this mean that you can use a VG310 as a voice gateway instead of a 29XX/39XX ISR? We are considering a roll-out design for some smaller sites where we will be using CUCM 10.5, VR 2921, VG310 and thought that we could use a VWIC3-1MFT-T1/E1 on the VG310 as back up to our 2921 in case of maintenance or outage.
Can someone please confirm whether or not, we can use a VG310 with VWIC3-1MFT-T1/E1 & enough DSPs to support a full PRI?
The EHWIC slot on the Cisco VG310 and Cisco VG320 chassis supports the following VICs and VWICs:
Thank you!!

Hi,
Q Can someone please confirm whether or not, we can use a VG310 with VWIC3-1MFT-T1/E1 & enough DSPs to support a full PRI?
A. Yes, it can support 1 Full PRI (Voice ONLY, no Data) as one can upgrade the DSPs from PVDM3-64 to all the way upto PVDM3-64-U-256 (Factory Upgrade, not sure about field upgrade)
Q Does this mean that you can use a VG310 as a voice gateway instead of a 29XX/39XX ISR?
A. Yes, however only Voice protocols will be supported, No WAN Data Cards are supported, neither do I envision any Routing Protocol .e.g. EIGRP / OSPF etc being supported (but there is a support for SL-VG3X0-DAT-K9 which is Data Lic, however I am not sure what features will be added if you are opting for that Lic)
Q We are considering a roll-out design for some smaller sites where we will be using CUCM 10.5, VR 2921, VG310 and thought that we could use a VWIC3-1MFT-T1/E1 on the VG310 as back up to our 2921 in case of maintenance or outage.
A. I dont see why it will/cannot be used to support Voice Gateway if you are connecting to PSTN using FXO/VWIC E1/T1 card
Btw, I built a Configuarion using CCW, which confirms that, enough DSPs can be put into it to support a full PRI (E1) and 24 Port FXS at the same time

Glad to know that we were helpful to you.
On a side note, I would want you to know that, VWIC / and FXO are supported only if you use it as MGCP Gateway (I haven't checked the H.323 or SIP GW Config part.

Great, thank you for confirming Wilson - very much appreciate your time and input... looks like we got a good option here.

That's great to know - we'd be using MGCP. Very helpful.

By the way it supports H323/SIP as well, refer to below:
Ref: http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/admin/10_0_1/ccmsys/CUCM_BK_SE5FCFB6_00_cucm-system-guide-100/CUCM_BK_SE5FCFB6_00_cucm-system-guide-100_chapter_0100110.html#CUCM_RF_V83D221A_00
The following table summarizes Cisco voice gateways that Cisco Unified Communications Manager supports with information about the supported signaling protocols, trunk interfaces, and port types.
Gateway Model | Supported Signaling Protocols | Trunk Interfaces | Port Types | Notes |
---|
Cisco VG310 | MGCP | T1/CAS/PRI E1/PRI | FXS/FXO/BRI | |
SCCP | FXS/BRI | |||
H.323 and SIP | T1/CAS/PRI E1/PRI | FXS/FXO/BRI |

Thank you for chiming in Terry - also very helpful to know we have H.323 & SIP as options.

Would you be willing to share your config? I am not finding any specifics on the configuration website on setting this up. And just worked with TAC and was told that this is not possible.
