Good experience of making phone calls through laptop / computer in the office, while travelling or working from home. It serves one of the key requirements of virtual office or working from home. Review collected by and hosted on G2.com.

Mobile app is a bit laggy sometimes. User interface could have been better. Review collected by and hosted on G2.com.

It has allowed me to administer in a much faster and more efficient way the attention to my clients, more than anything it has allowed me to monitor the calls that I receive in a much more practical and immediate way, since it allows me to carry several lines simultaneously and phone calls, so that I can improve the efficiency of all my sales and customer service processes, its interface has a fairly simple design that allows me to easily navigate throughout the entire system Review collected by and hosted on G2.com.

None actually, everything related to this system has seemed very useful Review collected by and hosted on G2.com.

The best thing about IP office is it comes as Hybrid system which includes Analog,digital and IP phones.IT has all the features like TDM,IP,SIP,VOIP,call centre up to 25 agents,video,wireless wifi support,recording,conferencing,etc. Review collected by and hosted on G2.com.

Avaya IP office comes at a quite high cost,as it includes call centre up to 25 agents also which makes it a bit costly than other Systems. Review collected by and hosted on G2.com.

what I like the most is hot desking allows users the non-exclusive use of a single extension. Users log in with their own identity in order to receive calls and access their voicemail and others facilities. For example, sales staff who visit the office infrequently may receive telephone and voicemail services without permanently assigned a physical extension. Review collected by and hosted on G2.com.

I consider that the support response times are very long which interferes with the timely attention of the requests, that is, incoming and outgoing calls that each user has, additionally affecting the response time also the level of service. This is a better opportunity that can give you a better answer for internal customer and end customer. Review collected by and hosted on G2.com.

Personally I don't have any negative other than the cost charged for the resources. Would be better if they expand widely. Review collected by and hosted on G2.com.

Avaya Communication Manager suits the needs of most contact centers. Support provided by Avaya is very good Review collected by and hosted on G2.com.

- CM lacks UDP support in SIP trunks, so you need an SBC; - in NAT environments CM can't work with static NAT, because it's not aware of things such as "external signaling address", "external media address", so you will either need SIP ALG which is not reliable or an SBC which works well with static NAT; - CM can't send Diversion header for transferred calls, so you need an SBC; - answering machine detection cannot be implemented solely by the means of CM. However, it can in theory be implemented using DMCC, but this would depend on AES which is not reliable, so you end up implementing it using SBC, which is easier than writing a software which uses DMCC; - low-level issues are extremely difficult to troubleshoot, so you basically get a black box; - CDR lacks essential information, for example: * it doesn't report final VDN unless you turn off some another essential field; * it doesn't report the skill through which the call was delivered to the agent; - CM doesn't have built-in call recording capability and Avaya Contact Recorder is extremely unreliable (sometimes because of AES, sometimes because of PostgreSQL, sometimes because ACR is just a poorly designed Java application), so you will end up implementing your own call recording solution using SBC with processing Avaya's CDR data; - contrary to CM, AES is extremely unreliable so the software depending on AES (such as Avaya Contact Recorder) is not reliable either; - BCMS lacks a lot of basic information such as agent's answered calls by skill; - low-level communication interface between CM and AES is not documented, so you can't replace AES with your own reliable software; - BPX functionality is almost non-existent, but you can create a software that manipulates coverage paths etc to offer the required functionality.

The service has a wide capacity to allow its users to manage their calls, internet, emails, faxes among many other channels. A clear advantage of this service is that it is available in the cloud which allows people to have easy access to the software.

Avaya's interface is very easy to use, gives users complete control of each operation they are working on and works very well. Review collected by and hosted on G2.com.

One disadvantage of Avaya Aura for inexperienced people is that its initial configuration is quite complex to carry out, so it is necessary to have people who know how the service works in order to configure it properly for the needs of each business. Another small disadvantage of this service is that it lacks options to share files with the customer, which sometimes is very necessary to fulfill some tasks.
